Mi Band + YubiKey wristband strap

Wristband for Xiaomi MiBand 3-6 and YubiKey USB-A.

Use TPU filament with 100% infill, without supports.

I think the buckle is most problematic spot. I afraid it might failure after a while, as it gets high impact on open-close - the single-wall cylinder gets squished between pin and keyring-hole of the yubikey.

That is the only solution I found to have yubikey holder as small as possible.

Unfortunately I didn't find how to make an adjustable length (with multiple holes).

Therefore I prepared a fixed-size options.

How to pick proper stl:

1. Measure your wrist in place where you wear your band. Use soft measure tape.
2. Add 85-90mm to your result - that's a wristband length you gonna pick for print.

Example:

My wrist is 175mm => 175+85 = 260.

What leads me to printmibandyubikey_261mm.stl for tighter option. If I want more loose option, then I add 90, what resultsmibandyubikey_265mm.stl.

After few hours/days you might reconsider to print another size. :-)

I used ERYONE TPU filament(use amazon search forB07WK54WXB. I can't post link here without getting replaced by thingiverse with some affilate injection - the price got increased more than 3 times :-( ).

I find ERYONE TPU pretty strong and durable: I tried to open-close the buckle over than 150 times, and didn't find any wear-out signs. Hope it will last longer than several months, which I find pretty okay to reprint periodically.

As a pin - one may use an aluminium pin from an original Mi-Band strap.
