If adjustments are needed, just let me know and I'll try fix them. If anyone needs this for a different size just let me know and I'll try to make another version but look into pipe fittings or reducers/(increasers?) first at your local hardware store as it may be cheaper/faster than printing a large version out.I like designing models without the need of supports so just orient the pieces correctly and you should be set, although I would print at 101%-102.5% size to account for your print tolerances as the ID and OD are 2.5 inches exactly (e.g. not 2.51 in or 2.505 in)   MALE/FEMALE COUPLER: I prefer PETG myself as it doesn't warp on me is elastic enough to not shatter if you drop it on concrete but I'm sure ABS/PLA will work fine as well if you can print them easily. The angled coupler was only made for my table saw since the normal female one flanges would interfere with the side of the saw; print one if you think you need it or let me know if it needs changes.*GASKET: It should be printed in any rubber like filament like TPU and then glued on but a gasket isn't necessary but it is a little better with suction. HARDWARE: Only four 5mm Hex bolts (20mm length/slightly longer is fine) are needed and 1 hose clamp unless you have multiple hoses.INSTALLATION: After printing the couplers and optional gasket thread the bolts into the male coupler until they are catching with the female flanges and then tighten or loosen the bolts depending on how tight they are when attached. The female couplers depending on the fit can be glued on or friction fit.Let me know if there are problems and if there are I apologize for wasting your filament and printer time as I know these can take a while and having a part being slightly too small or large can be frustrating.
