Clamp

To assemble the clamp, you will additionally need:

Round M6 furniture nut (preferably 18-20mm long)
M6-100mm threaded rod
M6 coupling nut
M6-25 bolt
M6 nut
Two M6 washers with a wide head
I printed it using PLA plastic and achieved the desired result. However, if higher strength is required, it is better to use more durable plastics, such as nylon.
