Snap-in V-slot Covers for Ender 3 Power Supply Rail

thingiverse

I really like the snap-in v-slot covers by MoltenMess since you do not have to take anything apart to install or remove them. For most of the covers I was able to re-size the covers to fit. The v-slot with the power supply screws was a problem, since the channel is blocked by the screws. I used Fusion 360 (with much trial and error) to create a hole in the channel inserts, allowing the cover to fit over the screw. These are sized for an Ender 3. The cover with the hole at 29 mm goes on the top, the cover with the hole at 79 mm goes on the bottom.
