This printable wool winder creates center-pull balls from raw hanks of yarn, it must be used in combination with a yarn swift, I will work on a printable swift in the future.
I designed this winder for my mother who was having troubles with her current ball winder, a new equivalent winder was priced around $50. I felt like I could design and make a better winder for only a few $ in purchased parts (most I had around) and plastic. Plus I know how it works so if it breaks I can fix it.
The winders function is pretty simple but really fun to watch. The motion of the winder can be explained as such. The hand crank, when turned causes the center carriage mechanism to rotate around a stationary cone. The motion of the carriage in combination with the stationary cone causes the winding spindle to rotate about its axis. The winding spindle completes one rotation for every nine rotations of the hand crank. The dual spinning motion of the carriage and the spindle is what causes the yarn to take the form of a cylinder.

To build the winder you will need a few non-printable parts.

You will need all of the bearings, I will attempt to explain the operation of the mechanism.
Consider the drive cone as stationary in relation to the base, it does not rotate as it is fixed to the main axle. The driven pulley is fixed around the main axle using two ball bearings allowing it to rotate about the axle. The carriage is fixed to the driven pulley with two screws causing it to rotate about the main axle with the driven pulley. The spindle base is fixed to the carriage using two smaller bearings allowing it to rotate independently of the carriage. The spindle base has an o-ring tire fixed in a groove, this o-ring tire makes contact with the drive cone causing the spindle base to rotate with the carriage. The spring between the drive cone and driven pulley is for increasing the friction between the spindle tire and drive cone, the carriage and spindle mechanism is not heavy enough on its own to ensure constant motion. The carriage rotates aprox 10-1/4 times for every rotation of the spindle base.
I hope this explanation makes sense and clears things up, if not let me know and I can post a video detailing the operation.
Hello, I'd like to make this wool-winder but there is one thing in the assembly I don't understand : there is a ball bearing enabling rotation between the spindle base and the carriage and then there is the drive cone supported by the spring which disable this rotation. So I don't understand what's the bearing purpose ? Can I just fix the spindle base on the carriage ?
I apologize if the instructions were unclear, I have added a note in the instructions section.. You only need a small portion of the spring to load up the cartridge. I have been cutting about 10mm of the spring off, just slip the spring over a scrap dowel or m8 threaded rod and use a dremel to cut the spring to length. The bonus is one spring can be used to make several winders. Let me know if you have any other questions.

NOTE: You will only need aprox 10mm of the spring.
* I reccomend slipping the spring over a scrap piece of 8mm threaded rod and using a rotary tool to cleanly cut the section of spring you need.
* Alternativly you can use a pair of side cutters and jam them in between the coils, I do not reccomend this method since you usually just end up chasing pieces of spring all around the shop and bending up the spring in the process.
