carabiner pulley

Pulley for a carabiner. Make sure to use this on a symmetrical carabiner and not a D shaped biner. Fits tight on my carabiners.

* default rope diameter = 15mm
* default pulley diameter = 39mm
* default pulley width = 21mm
* default center hole diameter = 15mm

If you make the pulley diameter too large, it may not fit on your carabiners.
If you make the pulley too wide, it may not turn corners on the carabiner without changing the center hole diameter.

The higher the infill, the stronger it will be. Don't use this for human safety.
