I bought one of those fabric tape measures a while back because they are fantastically useful for measuring oddly shaped things or perimeters. The problem is that they get tangled and bent faster than a neatly coiled pile of usb cables.
This device has a few features that I think are nice:
- It has a slot in it at an angle so that you can easily slide one end of the tape in and start coiling.
- There are two dimples in the side, this lets you hold it between your thumb and forefinger which makes it easy to coil and uncoil the tape.
- The ring is a little snug at first (I made it that way to accommodate many thicknesses of tape), so you might have to adjust it by cutting off a bit of the plastic on the inside arches with an exacto knife. This does make for a really nice fit though.
It is recommended to print both parts separate as skeinforge had some weirdness on my end when generating the combined stl.
