(Check out the derivative thing which I find works better)

Trying to sort out the mess of cables on my desk. The name is a reflection on the shape of the hub, which is the result of trying to maximize the bending radius of the cable.

Of course the OpenSCAD sources are fully parametric but comments are lacking...

Update: Updated scad file before first print to reduce overhangs on the lid.

Update2: Made two of these spools now, and not entirely satisfied... This design is too weak to work well with less flexible cables. Also, unwinding is a pain because the cable tends to unwind inside the spool making it jam. Next, I will try a detachable lid that snaps over the cable.

Print lid and base, snap together. A quick sanding and some grease makes it turn smoothly. Stls are tuned for walls of two perimeters thickness and an extrusion width of 0.48 mm. Rather thin but works quite well

To insert cable, line up the lid so that the cable can be inserted through the center. Hold the outside and wind by inserting thumb and index finger of your other hand in the openings in the center part and twist.
