Fireball Tool Small Square Tabs Gridfinity Holder

This is a basic tray to hold the accessories included with the 4" Monster square (which is the smallest size they offer) from Fireball tool.  It fits all of the tabs and thumbscrews included with one of the squares into 1x2 squares.  I think the smallest versions of the other Fireball squares include the same tab and thumbscrew kit, so this should work for those as well.  The tabs are the same size as those included with the Minion square kit, with the addition of an "L" tab.  As mentioned, the Monster square I have that came with these is the 4" size; I don't know at what size they change over to including the larger tabs.  But either way I have you covered, see this other model for the larger tab kit.

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.  This model includes sacrificial “mouse ears” in the CAD to give the ends more surface area to help prevent them warping off the bed.  They're not really needed, and I would not have normally added them to a 1x2 Gridfinity holder, but I cut this one down and modified it from the 1x3 holder for the Minion square tabs.  It was just easier to add mouse ears to the cut off end, than to remove them from the other end.  They won't hurt anything, and may be beneficial if you're printing in ABS or similar.  They 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.
