Adjustable Bowden clamp / shim redone

Tighten your Bowden tube in place, to fix/improve retraction! YOU NEED TO MEASURE HOW FAR OUT THE WHITE KNIFE-RING WILL GO AND MAKE THE SHIM HOLD IT IN PLACE. (see pics) Included: 2mm, 2.5mm and a 5mm version so you can cut off the bottom as much as you need during slicing. This shim is easier to handle, lodge, dislodge and find (just hang it on the screw using the hole).
