Small potatoes ... but I just printed up this shop vac hose adapter so I can stick some 1" hose in the fridge condenser coils and clean them out.
Also works good for vacuuming garbage out of trunk wells, the bottom of doors and below the quarter windows.
Put a taper in so the hoses snug up as you push them in. Printed in TPU. Beats the heck out of the duct taped mess I was using before
