Printed with sunlu PLA at 0.3mm layer hight, 98.5% shrinkage
Took me 40 min per part to print
Snaps together nicely without any adjustments
Has a wiggle, I shouldn't have set shrinkage (edited)

Might have been my print, but it was too tight overall.
It was really difficult to pry out the calipers. I think that might have been fixed in the current version since I printed mine quite a while ago.
Also, the fit between the two parts of the case was so tight I couldn't really get it open easily. I had to open it from the top and "peel" it open, which would lever the edge at the bottom into the space between the magnet block and the wall.
As a general observation, it might be better to design so that the clamping is tight only in defined places instead of all around. That makes use easier, and I could also sand down the clamping bits if my print is a little too tight (as it seems to be).
Still, considering how long I had my calipers, I was quite impressed how neatly they fit into this case! :-)
