Wire Straightener

Wire straightening hand tool. Two colors are shown for clarity.

All press-fit parts. No supports are needed, but I did use a 3 mm brim. Also, I placed the three "rollers" close together so their brims touched. The idea is to create an even larger adhesion layer.

There are two roller styles. "Wire Straightener-Roller-3" has three "doughnuts." "Wire Straightener-Roller-4" has four. Notice in the photos that one of the two Roller-4s is flipped compared to the other.

There are two link lengths. Print only one of the lengths. "Wire Straightener-24-30 AWG Link" holds the rollers apart just far enough that the doughnuts don't touch. "Wire Straightener-18-24 AWG Link" holds the rollers a bit farther apart to fit larger gauge wires. These two lengths were determined empirically (by trial and error) using a very small sample of wires. Your printer's characteristics and the insulation variations of your wires will likely affect performance.
