This is a basic Gridfinity tray to hold the 3" extension block from the Fireball Tool 3/4" fixturing system, part number FA75-MBV302-BDK. I thought about orienting these vertically to save a little bit of drawer space for use in tall drawers, but ultimately I decided against this, because the fixtures are heavy, and if you pack too many of them into a typical tool chest drawer, you'll probably be overloading the 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.
