Gridfinity rack for 8 small wrenches or tweezers

2x2 Gridfinity rack for 8 small wrenches or tweezers.

I used a 0.2mm layer height with a 0.4mm nozzle.

Included is the f3d file 

(modified from the original by Zack Freedman. 
The rack height is 30 mm shorter than the original.
The bottom part is unmodified from the original.)

It is a two-part model, that has to be glued together.
