MAKITA 36V (18Vx2) Holder

The aim is to hold the Blower snuggly but easily removable. There's a fine line between great and bad. The first problem I had was measuring it, as mine wasn't perfectly round but after a few tries I think it's good. Hopefully your settings will be fine.
I used ABS on my last attempt with a .6mm nozzle, .3mm layer height will get you between 2 to 3 hours of print time with 30mtrs of 1.75 filament.
It's possible the print conditions/speed could effect the outcome, as it pulls the inner diameter inwards.
I've included a test fit cross section of the part to print out before printing. The section represent the first ring on the blower. So, if it fits too snuggly just make the print larger. I hope it works for you.
If you have an enclosed printer for ABS 250-245* nozzle and 100-95c bed, print time around 2h:15m, it should give you perfect results out of the box.
It may print with a line around the middle from lazy topology but it won't effect the strength
