Just finished my latest Yoshi keychain! 🦖✨
I wanted the cute multicolor look but hated the idea of endless filament changes for the invisible middle layers. I optimized this model so that the internal structure prints in a single color, saving tons of time and reducing waste without losing any of the exterior detail.
Perfect for a quick gift or to organize your keys. Check it out and let me know what you think! #BambuLab #MakerWorld #Yoshi #3DPrinting

Toby was my in-laws’ faithful companion for many years. When he passed away, I wanted to honor his joyful spirit and the love he brought to our family. I created this keychain from a real photo of Toby, turning him into a little flying angel so we can always carry his memory with us.
This is my first model on MakerWorld, and I hope it brings comfort and smiles to anyone who has loved a pet. Feel free to print it, customize the colors to match your own dog.

Printed these multiplication tables for my son and my niece — they loved them and are excited to use them for their math exam this week 🤓📚. Even with a 0.4 mm nozzle the numbers came out clear and very legible. I used a few drops of super glue to join the two main pieces, and the AMS setup worked great since the color changes are only in the lower layers. For the two small red sliders I needed to use a pair of pliers to press them together, but it wasn’t a problem at all. Super fun and practical educational print!

My first print in PETG! Really happy with how it turned out—it looks strong, clean, and does exactly what I needed: a custom stand for my Lenovo LOQ. Simple design, solid result.

Printed this dual stand for a laptop + iPad and it turned out awesome! The print feels very strong and the design looks great. I only needed a few drops of super glue to fix the white parts onto the blue base and now it’s rock solid. Really happy with how it came out.

Such a fun and creative coaster design! My son absolutely loved it, and it came out really cute with the Pokémon look. Print was smooth and the details stand out nicely.

Really sturdy print! 💪 I used marble PLA for the outer shell and metallic blue PETG for the inner structure. Had some challenges printing the inner part because of the intricate design, but that was mostly due to my own skills and the iterative process of dialing in settings for this PETG. In the end, it came out great and feels super solid!

Absolutely loved this print!! 🎃 The design is super clever—only two filament swaps, yet thanks to the layer differences and the open spaces in the final black section, you get this amazing combined orange-and-black look all around. Such a cool and well-thought-out decoration. 🖤🧡 Boost well deserved!

Great model and very useful stand! At first I broke a few of the horizontal supports when tightening them (probably because I used silk double-color PLA), but I solved it by increasing the infill density in that section. Now it works perfectly and looks really nice.

Scaled the funnel up to 127.38% and it turned out perfect for pouring the 8LB Tuxiya silica gel beads. Sturdy print and super practical—worked flawlessly!

Simple but very cool print! The coin came out clean and solid, with nice edges and a smooth finish. Perfect as a token piece and it really pops in bright yellow.

Really fun multi-color print (With no AMS) and the parts fit together nicely overall. The only tricky part was the small cubes used to connect the hands—they were a bit tight, so I had to reprint them at 98% to make the assembly smoother. Still, the final result looks great and I’m very happy with how it turned out!

This Eiffel Tower model came out great! I had the chance to photograph it next to a life-size replica, and the contrast really makes the details pop. Clean layers and a very satisfying print

Great design! Works perfectly and, unlike other clips I’ve tried, it doesn’t damage or punch holes in the vacuum bags. The surface stays flat and sealed, so the spool storage remains airtight. Simple and very effective.

I think you’re not getting enough credit for this profile. I was struggling with those round models that sit in the middle of the spool and saw no effect when storing them in vacuum bags. I started to suspect exactly what you describe here. Now I’m printing all of them in the same color as the filament, with the curved part in transparent so I can easily check if the silica gel is still good. Great job!!

literally my second print (just after Benchy) and it works as described. I probably will print a bigger model in the future but in the meantime this one is fulfilling its purpose. thanks!!
