Lazy Kate

This video shows how this Lazy Kate is used.

A lazy kate is generally used to hold bobbins while you ply yarn on a spinning wheel.  This design is a colapsable design that fits pieces together and uses magnets to make them more user friendly.

These 3D printable files are all the files I use with the injection molded version of the EEW Lazy Kate that I sell on my Dreaming Robots store.

Some of the parts like the 3/8 and ¼ inch rods generally won't 3D print very well (injection molding them works much better since that doesn't have layers).  That is why for these 3D files I various rodHole parts ranging from 6mm to 8mm.  These are designed so you can stick a knitting needle into those parts and these work better when 3D printing so I recommend trying those if you are 3D printing the rods.

Here is a list of additional parts you'll need if you want all the features to work (though you can get a basic lazy kate without these).  I don't have links for them because I bulk order the items from a factory and they don't direct to sell to consumers.  I don't want to link to items that I haven't tested, but I suspect you can quickly find most of these online.  Hopefully someone will find and test parts that work and then place them in the comments.

1. Oring (EPDM #203 70-hardness o-ring) (3/8 inch)
2. Oring (EPDM #201 70-hardness o-ring) (1/4 inch)
3. Elastic Brake (1.6mm elastic cord - 25 cm long)
4. Magnets 5mm diameter 6mm long cylinder N42
5. 8mm diameter 1.5mm thick rubber feet (Same as Cone Winder)

The reason I'm putting these files online are twofold.  First I want my customers to be able to print replacement parts (or certain parts in different colors).  Second I want people who don't want to buy my EEW Lazy Kate to have the option to make your own.  That said if you want to support me check out my store and see the types of fiber tools I make.  https://www.dreamingrobots.com/

If you are selling these parts please just call them a “lazy kate”.  I'm reserving the “EEW Lazy Kate” name for the injection molded version I sell on my website.
