Weblock

thingiverse

To build an easy-to-use weblock, consider combining a metal tube with a shackle. I personally prefer using a tube with a 25mm diameter and a thickness of 1.7 mm. The threaded rod used in this setup has a M5 thread size, which is equivalent to a 5mm diameter. To prevent the tube from getting lost, include a small rope as part of the design. Since there's a minimal support requirement during printing, you can print this object without any additional support structures. One notable exception is a small portion that may need to be broken off before assembly.
