I took your parts and modified them a bit for resin printing. I twisted the hex pattern in the knob to allow the hex key to fit and bend into the notch. I also added a hex inset in the front bezel to accept a m4 hex nut glued in (instead of melted). I also changed the two screw towers (not sure the official name) that were meant for heat inserts and made them solid cylinders with a 2.7mm hole that I hope will accept a M3 screw direct screwed into the resin. I also enlarged the holes on the back plate to accept the new M3 screws in the bottom (I believe you had M2 screws in the bottom spots). Once they arrive and I confirm they work, properly, I will share the STLs.
