Summary

Suddenly found that they have a lot of sleeves, from 4mm-13mm, a total of 11, and 2 hexagonal connecting rods, so I designed this bracket.

This bracket makes it easy to place these sleeves and connecting rods.
The outer diameter of the sleeve is:
12mm, 6;
13/14/16/16/17, one for each of the five above.

Welcome to print and use.
