This is a 3D printed yarn ball winder i designed for my mother. It requires only a few non-printed parts such as bearings, screws & o-rings. The design and instructions are available www.thingiverse.com/thing:13816
Adding a motor is certainly possible, there are several commercial units available that are motorized. I never motorized my winder because there are downsides to motorizing, one of which is it becomes a little difficult to tell when the yarn skips. Get a few skips in the middle of winding and your center pull ball becomes useless.
As a knitter, I love this. I'd like some way to be able to attach a small electric motor to the yarn winder, could you do this? (the motor attachment, not the motor.)
Hello Danyelliebell, I apologize for the delayed response, I was in the process of temporarily moving from the US to Germany and missed your comment. If you would like a yarn winder you can certainly commission me to build one for you. Just send me an e-mail and we can work out the details. george.dundee@gmail.com
Taran Agnew, are there specific parts you are thinking about not printing? Pretty much every part needs to be printed with the exception of maybe the handles and yarn guide. If you had access to a wood lathe you could probably turn your own drive pulley.
