Heavy-duty Y belt tension hotbed holder

thingiverse

I needed a way to hook my Y belt onto my custom printer hot bed. I designed this to allow tightening and uses M5 square nuts embedded in the print to be strong. The M5 holes in the bed are 20 mm apart. The "B" version have through holes for the 5mm bolts. I use "pause at height" to stop the print at the last layer of the nut hole.There's no way to do it while it prints since the head will be in the way. The nuts I used were square M5 nuts 8mm wide on two sides and 4mm high. https://www.aliexpress.com/item/1005003184644320.html
