There are 3 strap lengths are 200, 250, and 300mm. All of them are 12.7mm (½") wide by 2mm thick.

Simply print one of the strap sizes and either the holder with support or without, either work, I just know some people like the holes to be as round as possible.

There are some interlocks in the holder, so you will have to push a little bit to get the strap into the holder, but once in the holder, it does provide good support and the strap does not come out very easily.

Pictures show the “natural” state when bent into the holder.

200mm - roughly 3.5" (89mm) x 1.75" (44mm)

250mm - roughly 4.5" (114mm) x 2" (50mm)

300mm - roughly 5.25" (133mm) x 2.5" (63.5)

If you would like a different length just reach out and we can get one added.
