Summary

The fasteners are designed for a 25 mm thick polypropylene pipe. A 12 mm screw (or longer) with an M3 nut is used to fasten the clamps to the pipe. To fasten the equipment, M3 nuts are pressed/soldered into the clamp and screwed with 10 mm screws. Such designs allow for stability in all degrees of freedom.

There is a hole in the clamps under the equipment for wires to connect sensors. To do this, you need to fasten the clamp in the right place and drill the pipe with a 6 mm drill.
