Summary

This is a coupler I designed for connecting my chop saw to my shop vac. It can also be used to convert standard hose sizes to standard PVC sizes (so you can rig up your shop vacuum system using cheap PVC instead of the hose.

Future edits will include engraving of sizes on the coupler, and some useful pre-rendered STLs.

The 57.5to47 file couples a 2" to a 1.5"? (large shop vac to medium shop vac)
The 61to53.5 file couples a 2" PVC fitting to the INSIDE of MY 2" vacuum hose - your vacuum hose may be thicker/thinner.

I printed mine in ABS on FAST (150μm at 15%) so these dimensions take into account the shrinkage of ABS.

EDIT (4SEPT2021): Added parameter to customize angle - default still set to 90°. Angle is measured from "Straight" to the tapered output. Also fixed an error in code that allows you to adjust the taper thickness.
