Materials:
Smooth dowel rods made of beech wood are suitable as round bars (tested 6mm, 8mm, and 15mm).
For screwing, M3 wood screws without shaft and with countersunk head are suitable. The length should be at least ½ of the diameter.
A thin steel wire rope (1-2mm) can be used for tensile force absorption.
