Proper Printing Portal Mod : Y Axis Belt Tensioner

thingiverse

Uses two M5 x.8 nuts and one M5 x 25 bolt for the knob and M5 x 25 for the pulley. Recommended using a soldering iron to press-fit the hardware!! Put a dab of superglue on the face of the plastic where you are inserting into then then press-fit the hardware into the parts using a soldering iron! Do the nut for the pulley last, because you have to slide it into the body first. For the nut into the pulley body, heat up the nut until to see it slide in. Then use a screwdriver that's about the similar diameter as the nut to press it in immediately. The nut won't be going anywhere after that! Similarly, you can use a bolt to pull it through from the other end. But don't leave the bolt in while you're heating up the nut. You'll heat up the bolt too and burn yourself!!
