Belay Helper

thingiverse

I stop my carabiner from spinning around while belaying with this device, heavily inspired by DMM's Belay Master. After field testing, I've revised the design and it now works effectively. So far, the design has been functional with all the DMM Twistlock HMS carabiners I've encountered at the climbing wall. Print Settings: Printer: Ralf's Box Printer Rafts: Doesn't Matter Supports: No Resolution: 0.25mm Infill: 25% Notes: Use rectilinear infill patterns instead of fancy ones, as they won't stiffen up the part excessively. Two perimeters are sufficient. Post-Printing: Pro Tip: Attach a rubber band or an o-ring on both sides of the hinge to keep it in place.
