Making a cheap, open source 3D space mouse with Arduino and 3D printing *V2 out*

Published at : 23 Dec 2025

At times this project was fun, and other times it was hell. Ultimately, by building on the fantastic work of others, we have an emulated Spacemouse that can be made for $20 of parts, thanks to Arduino and 3D printing. My version is a little bigger than I expected, so maybe a V2 is on the cards.

Thanks to Shiura and all of the other contributors to this great project.
