10.09.25 Update: Improved design to allow for better scaling and to improve printing at larger layer heights. I would still recommend printing at least 0.16mm for the best results. Also added support blockers to the .3mf to remove the fiddly and unnecessary supports in the leg joints. However, if you do scale up the model you may want to remove the support blockers to avoid failure. 

26.08.25 Update: Added a new print profile for a keychain version of Derpy 🐾 (apparently this was a feature some people were really eager for 👀). Now you can carry your Derpy with you the way it was meant to be done 💜

21.08.25 Update: Just added a single colour, .16mm layer print profile as an option for anyone that would prefer a speedier print. 

Derpy The Tiger

Meet Derpy — a fully articulated, print-in-place fidget inspired by K-POP Demon Hunters. 

• Print-in-place joints → no assembly required!  
• Fidget-approved → floppy, bendy, and highly poseable.
• Free model → because chaos should be shared with the world 💙
• Multi-color friendly → Derpy looks best with bold stripes, silly eyes, and pink toe beans, but feel free to go wild with your palette. Eyes are designed to be printed separately, so will need to be glued in. (STL File includes the eyes in place if you prefer to print all in one colour and paint) 

Whether you’re a K-POP lover, a fidget fiend, or just want a little demon energy on your shelf, Derpy is ready to pounce straight out of your printer.
