ShopVac coupler for 2.5 inch hose
thingiverse
This is a coupler for ShopVac 2.5 inch hose. Made in OpenSCAD. Initial size was based on measurements of a commercially purchased coupler. Needed to tweak for printing, so went through some trial and error to get the best sizes/taper. I've printed this and using with multiple hoses. Recently made, so the "test of time" has yet to come, but so far they are working well. Print Settings Printer Brand: LulzBot Printer: Mini Rafts: No Supports: No Resolution: .3 Infill: Probably Optional, I did 100% Notes: Printed with PLA. Other filaments should be fine too.
