This is a remix of the panel clips by FunFunBoy I printed for my Voron with 2020 extrusion.  It should work with any enclosed 3d printer.  Apparently some 6x3 magnets are larger than others.  Mine would not fit.  So the only change here are the enlarged holes for 6x3 magnets.  If you measure your magnets and they really do measure 6mm wide, you might want to try these out.
