Mingda Rock 3 Pro Bed Cable Strain Relief

thingiverse

I recently got a Mingda Rock 3 Pro and while I'm loving the printer, I didn't like how the bed wires had no strain relief after leaving the plug. I had a lot of curling of the wire and it just didn't seem like it would hold up over time, so I made a quick strain relief for it. It goes under the spring on the corner where the bed wires attach. I printed it out of ABS to withstand the bed heat, but I would guess PETG would be ok too depending on what you are printing as it isn't in direct contact with the bed. I just zip tied the wire to it. Note that though it looks kind of thick, it is hollow with ribs inside for strength. It attaches to the back left bed leveling bolt. I put it between the Y carriage and the spring so that it never touches the bed for heat purposes. It will slightly compress the spring, but didnt cause me an issue with leveling. My order from top to bottom is heated bed, spring, strain relief, Y carriage, bed leveling nut.
