Fishing Line Pulley for my DIY Ultimaker by mm-cnc Apr 6, 2013


2013-10-18: Changed the files to two new designs in pretty high resolution. They are 20mm in diameter and 33mm high. It has 15 turns. When you use 2 turn for driving (as I do in my Rostock since a year) 13 turns for movement will remain.

20mm * 3.1415 = 62,8mm
62,8 * 13 = 816mm --> This should be enough for your ultimaker.

Old Text:

I'm going to build my own derivate of an Ultimaker. I want to use the fishing line setup from my Rostock Delta Robot instead of a tooth belt. These are the two pulleys.
* one with a 8mm hole for the axis' and
* one with a 5mm hole for the stepper.

Feel free to ask any question.

So good luck for you!

I'd say that's excellent news for me, then :) I'll print a set of these tomorrow! (Got a motor mount printing right now :)

I'm using the same diameter in my woodstock!

Do you think that this pulley would be adequate travel for a Rostock? Money is a little tight, and if it would do the job, I'd like to run Spectra lines on the one I'm building. Looking forward to the extra speed and print volume over my Mendel.
