Hole adapter for dust collector / split collector

thingiverse

My vacuum was not powerful enough to keep the dust collector up the wall if not completly even. So i created a set of inserts to reduce the intake hole size - 24,20,16 and 12mm. The smaller the hole, the bigger the adhesion but also the smaller the collecting abilities. As they cost about 2cents each to print - try which fits you needs - start with the biggest one. Also i split the collector in two - much cheaper print with far less supports and overall stronger as collector and connector are both printed in optimal orientation. Downside is of course that it has to be glued back together.
