Multi-holder for tools and measuring instruments

This multi-holder attaches to any solid base using a standard clamp. Its use will make it easier to organize a workplace for repairing and setting up electronic equipment in any place, even the most inconvenient one.
Rubber gaskets must be used at the rod connection points to increase the friction force.
In the multi-holder demonstrated in the photo and video, I used a steel tube with a diameter of 10 mm, but the attached files contain clamp details for 15, 20, 25 mm rods.
M6 mounting bolts.
You need to put rubber rings and gaskets made of elastic material on the phone holder stops.
Of course, this universal unit for connecting two rods allows you to assemble more complex structures, for example, shelving and frames for apparatus cases.
