Fringe Twister

This is an almost completely printable four-threaded fringe twister with a gear ratio of 1:2 (rpm in:out). The largest part fits on a 120x120mm print bed. Since you most likely have a larger print bed, you might want to check out [martinqr]s baseplate remix: https://www.thingiverse.com/thing:4797640

I tried printing the clamps at first, but they where too weak, so you can either try to design your own or you can use crocodile clamps (alligator clips?.. Krokodilklemmen in German ;-) . To attach those, you have multiple options:

• glue them into the gear_small_w_hole.stl with epoxy or similar gluey stuff

• heat them up and melt them into the gear_small.stl (high infill) <- my method of choice

• design your own clamp/adaptor and combine it with small_gear.stl in your favorite cad software. The diameter of the gear shaft is 10.0mm.

I think the rest of the assembly is self explanatory. Happy twisting

Resolution:

0.1 to 0.15

Infill:

~25%

Notes:

Avoid blobs at all costs - especially at the gears. So turn on coasting, keep it slow and the layer hight low (0.1, 0.15 for the impatient).

You obviously need four of either the gear_small.stl or the gear_small_w_hole.stl (see summary above). Even if you only need two clamps I advise you to print all four gears for better stability of the assembly.
