I'm "reimagining" my i3 Mk2 with an Ultrabase heated bed and an aluminum y carriage plate (https://www.amazon.com/gp/product/B07B2649NN), using linear ball roller bearing slide blocks. The Ultrabase has a poorly-engineered solder connection that will not stand up to the constant motion of the y carriage. I needed to add a strain relief.

This strain relief bolts on using the roller bearing M4 screws, and has two zip tie slots to hold the cable securely, eliminating any movement at the solder joint.

UPDATE: After removing my bed leveling screws (completely unnecessary on a printer with auto bed sensing) I adjusted the strain relief to allow a smaller gap between the y axis plate and the heated bed. Also added a notch to allow for use with bearing u-bolts.
