Fourth Hand Cable Stretcher

Tool that helps ballpark the tension for adjusting shifting/braking.

Under development. May not work yet.

How I Designed This

Source image

Based on the Park Tool BT-2 tool.

Assembly

You'll need to print out all the STLs.

Need as many short M5 bolts & nuts as there are holes (5).

A small compression spring.

Assembly should be straightforward.
