Gridfinity 1x4x4u Dremel Bit Holder

Disclaimer: Please ignore the bad print quality in both the photos.  Bargain basement silk filament kept clogging/partially clogging the nozzle in first print, in second print the parts fan died causing warping, and ironing the surface didn't look very good either.   

Separate bit storage allows shorter print times, separating bits into types (sanding, polishing, cleaning), and/or having multiple color trays. 

This was done in Tinkercad by chopping up and rearranging the original model and Atucom's “adapter baseplates" which re-adds the magnet holes, which are filled in in Sacrilegor's model. 

V2: Fixed minor imperfections.  Added a shorter version, overall height of 20mm.  

V3: Base holes are now square bridging method to avoid ‘fallen rings.’
