Bowden Tube Clamp

Here's my idea of a Bowden Tube Clamp to help stop coupler chewing of the tube from constant back and forth movement.

Note: clamp part should fit snugly on tube prior to screwing down.

I found...
r4 clamp works for Capricorn tube and
r4a clamp works original tube.

send message of any questions, Thanks, and Happy Printing ;)
