Mini Bubble Spirit Level keychain

thingiverse

I got this little spirit level (15 x 15 x 40 mm) as a promotional gift and it was just lying around, so I turned it into a keychain.I had to make the internal dimensions a little larger at 15.4 x 40.4 mm so the spirit level would fit perfectly.Update: It's bad that you can't see the spirit level from the side, so I added holes on the sides.Update: request from ferraguar. i hope it works.
