UPDATE: the body failed after about eight months of use, and I realized that there was a weak corner in the design. I've updated part A to eliminate the flaw.

I was fed up of hand-rolling my boxing wraps after washing them, and wanted something that was smarter.

I didn't like what I saw on here, or even to purchase, and decided to design my own.

This will work with cotton or Mexican wraps up to 180" in length.

8% body, 20% spindle

I printed in two colors, with body parts red, and spindle white. But you can print however you like.

the parts are:

A: body/core
B: body/lid
C: spindle/core
D: spindle/knob

There is a 0.2mm recess on the base of both parts C and D to help facilitate them fitting together. Ideally, the two should push-fit tight, but it may be that there is a little under-size or over-size. Let me know how yours turns out and I can optimize.

The spindle can be delicate: don't put any stresses on it as you're removing the part from the print bed, and slide it through the hole in the lid as soon as you can... the lid will help a lot with durability.
