I designed this rechargeable parrot shower for my two birds. The original idea was simple: many parrots enjoy bathing, but a normal water bowl is easy to spill, and manual misting is not always convenient. I wanted to make a small shower that could sit inside the cage, run from the Rechargeable Power Kit, and be easy to clean after use.The final design is built around four main ideas:a quick-release power module, water tank, and printed filter for easier cleaninga magnetic-drive centrifugal pump, so the motor stays outside the water areause a ready-made transparent plastic sheet, as this will yield much better results than printing a transparent model.modular shower heads, so different water patterns can be swapped laterThe hardest part was the pump. I first tested small centrifugal pump prototypes, but the early versions did not provide enough head height. I also tried a peristaltic pump, but with the kit motor it had too little torque and the water output was small and uneven. After several rounds, I returned to the centrifugal pump idea and improved the pump body, added a better volute shape, enlarged the impeller slightly, and integrated the water channel with the printed body to reduce leakage and pressure loss.a early prototype Noise was another important challenge. Since this is meant for birds, it should not sound too harsh inside the cage. I tested TPU parts and found that using TPU only for the gear ring gave the best result: the noise dropped a lot, while the water output stayed almost unchanged. Printing more drivetrain parts in TPU reduced performance too much, so I kept the softer material only where it helped most.test with different materialsThe current version has passed full assembly and real-use testing. In one endurance test it ran for more than 250 minutes on a full charge before the continuous water flow gradually became dripping. Actual runtime may vary depending on print quality, lubricant, friction, and battery condition. I also added a filter after noticing that a small piece of debris could block one shower hole during testing. This project went through more iteration than I expected: pump efficiency, gear ratio, water sealing, magnetic coupling distance, noise, clogging, and shower hole spacing all needed adjustment. The latest shower head uses fewer, slightly larger holes than an earlier version, because dense water streams could merge together.I hope this design is useful for other bird owners and also interesting for anyone exploring small printed pumps and magnetic-drive mechanisms. Model link: https://makerworld.com/zh/models/2934071-budgie-shower-spa-mini-bird-bath-fountain#profileId-3285052

(model link: https://makerworld.com/en/models/2798526-the-double-ring-carousel-motorized#profileId-3112952)The Engineering Behind the Double Ring Motorized Carousel When MakerWorld announced the Rechargeable Power Kit Challenge, I knew exactly what I wanted to build: a classic, motorized carousel. The inspiration sparked from a cardboard prototype I built recently, which used three gears to drive two rings in opposite directions while creating a galloping motion for the horses. With that mechanical concept already in my head, I dove straight into CAD the moment my power kit arrived. Nailing the Base & Gear Mechanics To ensure perfect fitment, I imported the official 3D models of the electronics directly into my workspace. This allowed me to map out the tolerances precisely, and the massive base piece actually succeeded on its very first test print!The internal mechanisms, however, required some serious iteration: Tolerance Tweaks: My initial 0.15mm gear gap caused catching when the Z-seams aligned. Opening that gap to 0.2mm resulted in a smoother rotation. Gear Redesign: During early testing, I noticed the gears were binding. My solution was adding a secondary layer to the central gears to prevent direct friction between specific components, which instantly freed up the movement.The Big Problem: Weight vs. The N20 Motor As I moved up to the canopy, I hit a massive engineering roadblock. The upper assembly was simply too heavy (around 264 grams) for the N20 Worm Gear Motor. Since the challenge requires using the provided kit, brute-forcing it with a bigger motor simply wasn't an option.I knew a thrust bearing would absorb the downward load, letting the motor focus entirely on rotational torque. When I couldn't find a Maker's Supply bearing large enough to fit my existing geometry, I decided to engineer my own. By printing a custom track and dropping in ten 6mm Stainless Steel Balls (FA001), I created a “frictionless” base that carried the canopy's weight effortlessly. The Hard Choice: Form vs. Function With the main body spinning beautifully, I faced one final hurdle. The moment I placed the horses onto their wavy tracks, the motor stalled out. It just couldn't overcome the combined friction and the vertical lift required to push the horses up the slope. I tried everything: lubricating the tracks, widening tolerances, and printing at the absolute lowest layer heights. When nothing worked, I had to make a tough decision. Rather than delivering a stuttering, unreliable model, I scrapped the vertical motion and locked the horses in place. 1: Only wavy track2: Wavy track and bearing3 (Final Version): Only bearing Engineering is all about problem-solving and compromise. While I had to let go of one feature, it guaranteed a flawless, continuous spin for the final piece. After countless hours of troubleshooting, seeing this carousel light up and spin smoothly on my desk is incredibly rewarding!

Idea | Prototyping | ImplementationThe Spark: Honoring the Challenge. Being selected for the MakerWorld Limited Kit Challenge was a significant honor. I’ve always enjoyed browsing Maker’s Supply to see what sparks my imagination, but this challenge provided a specific focus: the Rechargeable Power Kit. I enjoy working within a set of rules, but my goal is always to push beyond the original intent of the components. I didn't want rotation just for the sake of movement; I wanted that motion to serve a purpose. The Idea: Bringing the Outdoors In The inspiration came from my home pond. I love the atmosphere—the sounds of moving water, the flowers, and the fish. My goal was to use the rechargeable power kit to recreate those soothing water sounds indoors. After researching various mill designs, I found a concept that felt right and began the transition from digital concept to physical reality. NO AI WAS USED TO MODEL - I DRAW AND PUSH/PULL EVERY LINE INSIDE SKETCHUP Prototyping: The Trial Phase The road to a functional model wasn't immediate. It took three weeks of constant iteration and many prototypes to get the internal mechanics right. This phase focused on the "gadgets and gizmos"—integrating the gears and the motor kit into a cohesive system. I was particularly inspired by the modular nature of these kits, which allows creators to build and expand their own miniature worlds. Implementation: The Final Result The final assembly, represents the successful marriage of mechanical engineering and natural aesthetics. By combining the motor-driven mill with landscaping and live plants, I achieved my goal of creating a functional, rechargeable piece of art. This project is just the beginning; I look forward to using a wider range of Maker's Supply tools to expand this world further.  Check out This model HERE - Thanks everyone! #Rechargeablepowerkit #Kitchallenge

When MakerWorld selected us, along with several other talented creators, during the last #KitChallenge for the #RechargeablePowerKit, we knew we wanted to use the opportunity to push ourselves into something we normally would have avoided. https://makerworld.com/en/models/2698922-giant-s-grove-marble-run#profileId-2991697  Marble runs have always been one of our favorite things to design, but we didn’t want to create another standard marble lift with a giant printed screw pushing marbles to the top. We became obsessed with the idea of using a marble pump system instead, even though they’re notoriously difficult to get working consistently.  One thing we’d encourage other makers to do is participate in those challenge discussions and drop ideas on the posts when they come up. Opportunities like this are really fun because they can push makers into experimenting with concepts they may never have tried otherwise.Inspiration from NatureOur kids have been completely into Minecraft lately. We kept thinking about blocky landscapes and terrain generation, but we didn’t want this to feel like just another square world. That led us toward thinking about hex geometry.  We became fascinated by the natural hex columns found in Giant’s Causeway in Ireland. The shapes almost feel artificial when you first see them, but they’re completely natural formations created by cooling volcanic basalt. When designing the rock formations, we initially tried manually varying the column heights, but it still felt too artificial. Eventually we wrote a small script to help randomize the rock heights so the landscape felt more organic.Credit: Pete Flynn - Google MapsOnce that clicked, we started carrying the hex language through the entire design. The stone base, the tree trunk, the canopy, and even the track structure all follow variations of that same geometric pattern language so the whole model feels connected together.  We wanted it to feel like a strange magical tree growing directly out of a hexagonal rock formation.The Marble Pump ChallengeThe hardest part by far was the lift mechanism.  We originally found inspiration while researching unusual marble lift systems and came across some incredible wooden marble pump builds on YouTube. One of them especially stuck with us because of how elegantly it moved marbles upward without relying on a large auger system.Credit VEProject1: https://www.youtube.com/watch?v=zCWnoSamN7gThat started a long process of experimentation. There were a lot of failed iterations trying to figure out the geometry, the timing, the angles, and how to reliably move marbles upward without jams. Tiny angle changes completely changed the reliability of the system.Many test to get smooth motion and marble movement. Eventually it started to click. Once the geometry finally came together, the system became surprisingly reliable. Even better, the Rechargeable Power Kit’s N20 motor had more than enough power to continuously lift the marbles through the system. Even though the base on this one is large, one of the things we’re most excited about now is how compact this style of lift could be compared to large printed screw elevators. We can already imagine future marble runs using this same concept in completely different ways.Designing for Future ExpansionAnother idea behind Giant’s Grove was designing it more like a platform than a single marble run. The acrylic tube section was intentionally designed so the internal flow paths could eventually become interchangeable. We plan to release the STEP file soon for the central tree trunk for anyone that wants to create their own designs for the marble path. Our hope is to create alternate internal modules in the future so makers could swap out entirely different marble flow systems while keeping the same outer structure.  That idea of modularity keeps making its way into our projects lately, and we think there’s a lot more room to explore there. Happy printing!
