Bio
I’m passionate about designing toys, tools, and decorative pieces while exploring new techniques to push the limits of 3D printing. My goal is to create models that are both fun and functional, optimized for easy printing with minimal or no supports, and straightforward assembly. Every design is thoroughly tested to ensure reliability, printability, and a great user experience.

I've gotten lots of requests for a WH40k bolter keychain blaster... Here it finally is! TGW please don't kill me. This is a tribute made with love for the WH40k universe!

I finally received my new Steam Controller, so of course I had to design a simple, yet stylish stand for it! #Newmodel #Gaming(Edited)

There aren't many interesting models for the MB001 Water Bladder, so I wanted to design something for it... Fallout is one of my favorite game series, and the fusion core is the perfect shape and size for a water bottle! "Introducing the Fusion Core Hydration Unit, a cutting-edge portable water system inspired by the same iconic power source that keeps your favorite power armor running strong. Now, that same bold, industrial design fuels you."

Keychain-sized, spring-powered "saber" fidget toy inspired by a certain sci-fi franchise. Simple to assemble, fun to play with! No need to break your wrist flicking your saber, just press the switch to extend the blade!

A new version of my Minigun Keychain that has a completely new firing mechanism with no need for an M3 bolt — it fires 6mm airsoft BBs by rotating the barrel assembly! It also comes with both a smaller stick magazine for 6 BBs and a bigger box magazine for 14 BBs. Comes with keychain magazine cap to carry the magazines, and an optional ridiculous crank attachment for ultimate fire rate!

A new, vastly improved version of my first keychain blaster! Finally there's a trigger, and it's functional! The M3 bolt requirement is gone as well, so you only need a small spring and some glue to assemble this.

I designed this ring with a lovely led-lighted crystal for my friend's daughter. It's a quick print and uses the Maker's Supply's Single LED Magnetic Control Switch Light.

I needed a small utility blade to always have with me, but the existing ones I found use the big utility blades that makes the whole tool big and clunky. I wanted something as small as possible, so I designed this retractable knife that uses any shap of hobby blade, the ones you probably have a box of for your x-acto knife. 🙂

I noticed I hadn't released my classic cartoony print-in-place toy car here, so here it is! The smaller versions are quick to print and work straight from the build plate, so no assembly required! Perfect toy to give away to kids!

Someone asked me if I would make a dueling set box for my Flintlock Pistol Keychains, so here it is! The box has print in place hinges and a latch with a little 1.75mm filament pin. The insert is printed separately so you can use your best comfy velvety filament for it so your flintlocks are comfy! Solve your beef with someone the old-fashioned way with this dueling set!

My puzzle-loving friend wanted a numeric cryptex, but I couldn't find one with ratcheted dials. We both hate trying to set the combination when the dials spin around wildly on their own… So I made my own cryptex, with ratcheted dials and no need for hardware to assemble! #Newmodel(Edited)

Functional little flintlock (musket) pistol keychain that shoots printable bullets. Detachable ramrod under the barrel is used to push the projectile into the barrel and after that it's ready to shoot! Ironically, this is probably my strongest keychain blaster to date. 😅

I'm making so many blasters that shoot BBs and other projectiles that ricochet and fly everywhere... Engaging the safety squints to protect my eyes can get tiring, so I designed these Safety Squints — printable safety glasses!

I wanted a bullet keychain, but what's the point of a bullet if it doesn't shoot? So this one fires by pressing the keychain clip in the back! This is a very quick and small print (~35min & 6,5g of filament) and you only need a small 5mm diameter spring to make it work! The bullet is also compatible with my Ringchaku chain, so you can use it as a Ringchaku fidget spinner as well! Just attach the chain instead of the keychain clip!

Merry Christmas & Happy New Year! Thank you for being part of my little corner here on MakerWorld and supporting me by downloading my designs and giving constructive feedback (and boosts)! I appreciate you all! ❤️ This end of the year was a little slower on the design release side than I had planned due to personal matters, but my New Year's resolution is to bring you more interesting and varied designs next year! I have a long to-do list of great ideas from both myself and the community here, on my Discord and Youtube channel... Stay tuned! I wish you lovely holidays — see you next year!

I wanted something a little different for my Christmas tree, so I designed this led-lit crystal ornament inspired by Dragon Age and its lyrium crystals! It's using Maker's Supply's magnetic switch leds — they're the perfect size and brightness to make these crystals look amazing!

A simple Christmas themed charm hairband I made to wear for a Christmas event. I thought I might as well release it here as well in case someone else finds it charming. 😄
