Thanks!

advertizing your own stuff without any facts is a bit rude, isn't it?

Don't you think, that this is a comparism between apples and pears? ;)
The sharp edges of the aluminium part will add much more stress to the fishing line. Just give it a try before bad-mouth something.

Instructions

You can insert 2 M3 nuts to fix this pulley on your stepper.
The inner hole for the Dyneema Line goes curved arround the hole for the stepper.

The initial idea did not work. To less windings.
I use it now with only two windings arround it and not going trough the middle hole. Works great with the right tension.

In normal use, you can only travel 300-400mm

you dont need to think about overlapping by using a fishline with diameter under 0,15mm....

For sure the one you posted isn't better. Have you ever tried my design? I use it since 2000 printing hours on my Woodstock/Rostock printer. The perfect guide reduces the stress for the fishing line dramatically.

I'd like to see the setup your using to hold these pulleys. Is the performance of this comparable to that of a hobbed driver? Cool idea man.
