    Embridery floss mini swift

    I've always thought that for winding embroidery floss onto bobbins, there should be a swift, similar how the ones for hanks of yarn. So here it is. A video of this thing in action can be found here.

    Required hardware

    • One 607-2RS bearing (Inner Diameter = 7 mm, Outer Diameter = 19 mm, Thickness = 6 mm)
    • One short M3 screw
    • 18 M2 x 5 mm sleeve nuts and matching screws (Alternatively M3 x 8 mm screws and corresponding nuts, but they might come loose with use)

    Assembly

    You need to print one of each part, except for the arms, where you need 6 each of both kinds.

    1. Take the axle and insert it into the clamp body through the threaded hole and into the smaller hole. Make sure the hexagon-shaped parts of the hole and the axle are aligned and then push it in as far as it'll go. You can later use the clamp to get it all the way flush.
    2. Take the printed clamp screw and screw it into the threaded hole of the clamp body.
    3. Take the clamp protector and put it on the clamp screw. If it doesn't go on easily, take a piece of wood or the edge of a table and attach the clamp. This will both push the protector in place as well as make sure the axle is all the way in and flush.
    4. From the top, put the stopper on the axle. This might be difficult - I used a pencil that didn't have an eraser to stretch open the stopper and guide it onto the axle.
    5. Assemble the main mechanism:
      1. Press the bearing into the hole in the top spinner. If you've got parallel pliers use them.
      2. Assemble three sets of arms using the sleeve nuts. Make sure you've got two outer arms on one side and two inner arms on the other. Take care to have both left-leaning arms on top and both right-leaning arms on the bottom.
      3. Attach the assembled arms to the top spinner with sleeve nuts. Make sure they are all oriented the same way and attached on the same side of the top spinner tabs.
      4. Do the same for the bottom spinner.
    6. Slide the main mechanism onto the axle.
    7. Carefully insert the M3 screw into the axle from the top. It will make sure the bearing is secure and can not slide off of the axle. Once that is achieved, you do not need to tighten the screw further.
