Description
Being less than enthusiastic about the VHB DIN mounts in the Voron 0.2 parts list and unable to find simple alternatives which seemed just right, here is my version.
Instead of fiddling with positioning sticky pads correctly, these mounts locate securely on the lower four screw positions holding the mid panel in place. The wide-spaced layout they make allows plenty of space for a cable raceway in the centre. Their extra rail width also allows a little lateral adjustment of the boards if narrow clips are used.
For my build, these were used to mount a Raspberry Pi 4B and a Bigtreetech SKR Pico.
Thanks to @alidaf for the excellent OpenSCAD DIN rail which this design is based on.
There are two separate, mirrored, models for each side.
ABS or ASA with the recommended Voron part printing guidelines, or similar equivalent - as long as they are strong and suitably heat resistant.
Print forward-side down (same as in .stl files.) The counterbore holes have overhang reliefs so no supports are needed.
Ideally, install these mounts at the same point as fitting the mid panel.
If the Pi and MCU are prepared with their clips, try them on so you can judge which pair of mounting holes set them at the preferred height.
Fit the cleats over the lower four holes indicated with M3x8 or M3x10 screws.
The stock Voron DIN clips and Raspberry Pi board mounts can be used, but good alternatives exist. I used Trev1ak's designs from https://www.thingiverse.com/thing:5278559 - because the boards can be fitted with M2.5 screws / nuts and not the M2 self-tappers indicated in the manual, which I didn't like using.
