This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/86htHl4dqkl
A tablet for use with a slot tire truer.
The dimensions are 180 mm X 140 mm X 23 mm
Prints also good with a scale of 0,93.
Then it is a bit smaller an fits also well with any slot tire truer.
But prints much faster. ;-)
