This instructable describes an easy and cheap way to make cable guides.
So let's get those moving CNC wires or mad-wire projects guided up!
Step 1: Materials & Tools
- Scalpell (or other knife with long sharp blade)
- Wooden stick (that fits inside the tube)
- Cutting pad
Tubes in different colors and diameter should be available at every home improvement market.
Step 2: Round and round
Now take your blade and "roll" it in a spiral way over the tube. The wooden stick serves as a good cutting surface.
Depending on the pitch of the cutting line the tube gets more flexible with shorter cut intervals and more stiff with wider intervals.
The more preasure you apply with the knife now the better. Else you will have to rework as the tube is not completely ut.
