I can’t tell if I just have very small hands or if it might be a bit smaller than 3×2 based on the finished product photos on Thingiverse haha. I have a friend with a 3D printer so I may ask him to test print me the case so I can mess around with it a bit.
I was thinking of making a little leather holster for it with straps to match my watchband. I really appreciate the offer of help with adding a mount, though! I can see myself finding a lot of other applications for this so I might have to take you up on that sometime.
