Description
This is a holder for my SP Air mini-beveler, in 3x3 Gridfinity squares. I bought this tool for deburring aluminum plate edges on my boat project. It came with an allen wrench for adjusting the depth of cut, and a torx wrench for rotating or replacing the carbide inserts, and a small wrench, the purpose of which I have not yet had occasion to discover. Plus a set of instructions that I haven't really looked at...
With the QD air fitting, it's a little too long for 3 squares, so I left the end open so the fitting can protrude into the empty space at the edge of my toolbox drawer, where there isn't enough width left for another row of squares. The included torx wrench also wasn't going to fit, so I substituted a typical "flag wrench" used for changing inserts on machine tools. I made the cutout generous enough that most flag wrenches should fit OK. There's a recess for the small wrench, and another recess where you can put spare in$ert$ (the replacement inserts from SP Air are way too expensive for what they are), the allen wrench, and the spare insert screws that are included with the tool.
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.
