A small funnel to facilitate bleeding radiators.  I have spent years doing this job with a round funnel that didn't fit between the radiator panel and the wall or between double panels.  One day it fell to bits - but now I have a printer so could make a better one.

The funnel is designed to accept a normal ½" hose so the funnel can drain into a bucket.

I printed it upright (hosetail down) and with support under the funnel.  I used PETG but PLA would have been fine.

Subsequent to making this funnel, I have had the time to design a fully integral bleed bottle/key assembly which allows one-handed bleeding in awkward spaces:  https://www.printables.com/model/1320841-radiator-bleed-key-bottle In my opinion it's an even better tool for the job.
