Gridfinity bin for two 150mm digital calipers. With holes for 6x2mm neodymium magnets. 

There are now three versions:

• Both calipers facing same direction (v2) - works well when the bin is partially covered such as in a drawer that does not open all the way. 
• One caliper facing each direction
• As above but split to fit a smaller build plate

The calipers modeled for are from Cocraft, but would fit any similar size digital calipers.
