The hot end cables were dragging along the bed & pushing on the heated bed cables, causing the bed to move up and down during a print. (Ender 3 v2).
So, I designed this little guide to hold the hot end cables up slightly so they don't interact with the bed. One side of the hook is chamfered so that the cables don't touch any sharp edges as they move. The guide slots into the frame of Ender/other 3d printers on the back left side.
If you want to cable tie the cables into the guide, then just make sure it has enough slack for the hot end to reach the top right of the print area before tying it.
It prints without supports, just make sure it's oriented with the long flat side down to the bed. Doesn't require supports.
