Description
The knob hosts heat insert fasteners for durability connected to the toggle lock with metric screws (links provided). I could not find 1/4" x 20 x 3/4" T-Track bolts, so I had to cut 1/4" x 20 x 1" down to 3/4" and slightly chamfer the cut ends to they threaded smooth.
Note: These updated parts fix minor errors and naming issues of previous ones. They are also centered and zeroed for the platform.
I will be adding an assortment of bases in the future (stay tuned!)
Links for hardware (I recommend using the same heat-press hardware as the parts are sized for a solid fit)

I worked the design so it was under 3/4" to clear bench tools. Using CAD and iterations of test fitting, I arrived at the final design. I think I finally figured out that when I design in SAE, the STL files need to be magnified 2540%, so hopefully these upload correct. I changed the units to Metric before the final STL export.
