Fireball Tool Tacking Bolts/Alignment Pins Gridfinity Holder

This is a basic Gridfinity tray to hold either the tacking bolts (p/n FA75-BTA200), or the alignment pins (p/n FA75-BTP200-4BDK) from the Fireball Tool 3/4" fixturing system. There are lots of different ways these could be oriented; I opted to do them vertically in 4 squares, because both parts are sold in packs of 4.  If you want to use these for the tacking bolts, it's going to take a fairly tall drawer.

Like my other Gridfinity models, the base is altered to accept 6x3 magnets as a press fit, with the upper surface of the magnet holes modified to make the slicer bridge across correctly for a clean result.  Due to the size of this model, I have included sacrificial “mouse ears” in the CAD to give the ends more surface area to help prevent them warping off the bed.  These will need to be removed after printing.

The unit pictured was printed out of Overture PLA on my Bear upgraded Mk3S+, using a 0.6mm nozzle, at 0.3mm layer height.

Edited to add, 01SEP26:

When the drawers I ordered for my fixtures finally arrived, I found that the tacking bolts just barely wouldn't clear when closing the drawer, stored in the original bin.  When I build a Gridfinity holder, I generally start with a template file for the base in the size needed, and build up from there.  Looking at the holder, I realized that with the way the recesses were arranged roughly centered on the grid squares, I could cut them deeper without interfering with the geometry of the base.  So I cut them 4mm deeper, and that allowed it to fit in the drawer with the tacking bolts.

I have uploaded the new file here as version 1.1.  I left the original 1.0 version available, in case for some reason you want your pins to stick up by another 4mm.
