I present to you the Gridfinity Mitutoyo caliper holder Case. This case holds you're caliper in place with magnets so it doesn't fall out of the box. also the tight fit of the box should help with keeping it in place. this uses 6x2 magnets for the calipers and the lid that need to be glued in. There is also a non Gridfinity case available. This print was to big for my printer to handle so i had to cut it in 2 in the slicer and glue it together.

Some specs:

• 2x6x5U gridfinity size with lid. without lid its 4U high. 
• 251.5 x 83.5 x 15 mm (no lid). 251.5 x 83.5 x 21.5mm (no lid). 
• magnet holes are 6.2 x 2 mm.
• 9 magnets case. 4 magnets lid. 13 magnets total.
• printed at 0.2 mm with a 0.6 mm nozzle.
