Belt holder with tension adjustment

thingiverse

I'm getting ready to upgrade my delta printer with a Belt holder that's easy to adjust for tension. It comes with a complete set of other essential parts. Other Parts: (one set) M3 Hex nuts - I'll need three of these. Outer M3 Hex Head, 20mm long - just one is required. Inner Hex head screw, M3 x 25mm - one is enough. Inner Hex head screw, M3 x 40mm - two are needed to complete the upgrade. Self-locking M3 nuts for 2020 aluminum - I'll need four of these. 623ZZ bearings - two will be sufficient for my printer. M3 x 0.7mm washers - five should do the trick. My delta printer requires three sets of these essential parts.
