When I first got my suck it! dust boot I immediately set upon destroying it. It came free as part of a Onefinity sale so I didn't realize how expensive they were. After looking for a suitable replacement boot to buy I quickly noticed that the thing I wanted didn't exist. So I made it exist.
Uses the original suck it brush or equivalent and heat set inserts which I purchased from amazon. You can click the link or search for #6-32 heat set inserts, get the short ones.
