Gridfinity Diamond Hole Bits Holder

I have a big set of diamond-coated hole bits, as well as several extra that once belonged to other sets. I wanted a Gridfinity solution that would hold them all. I initially tried converting a bit holder from Thingiverse to work with Gridfinity, but was unhappy with the amount of material it would take so I ended up remaking it inversely…instead of a hole in a solid surface, this model has upright hollow tubes for slotting in the set instead. Since there was extra space after sizing it for a 2x4 Gridfinity piece, I added some extra grooves and holes for additional random bits or tools. Works perfectly for what I needed, so I thought I would share.I printed this with a .8 nozzle on my P1S, using Elegood Rapid PETG. I've been experimenting with print profiles for speed, so I hope that saved properly to this model. This is my first creation and upload to Makerworld, so please let me know if you have any suggestions (but also be gentle ;) ) I've gotten up to 28mm^3 volumetric speed
