Smallpipe chanter cap

This is a chanter cap for smallpipes, specifically John Walsh “retro” pipes. This model may work for many other smallpipe brands, I guess you won't know until you try?The screw hole is threaded and designed for a 1/4-20 screw. I will be honest here, 3d printers don't do great with small threaded holes. I use a 1/4-20 reamer after the print, and I finish the chanter cap with a 1/4-20 nylon knurled screw from the hardware store. If you don't have a reamer (most people won't), I think that just carefully force-screwing a metal 1/4-20 bolt through the printed hole would help clean it up nicely.
