I needed a better support for my funnels - easier and faster to 3D print than to order from the catalog.
The first version was a bit small, version 2 has a 40mm support opening.
(Version 1 is the only one I have printed, and is shown in the photos).

Print support will be needed for version 2, but v1 can print without.

UPDATE: added Funnel Support_03 file with a cylinder "holder" instead of the polygon - again, untested - but should give a little better support. Slightly adjusted the position of the center pin for locking along thicker stand rods (or less flexible plastics).

Doesn't Matter

0.20 mm

10% - 15%

support needed for v2.
I used a raft - optional. Helper discs might be useful if no raft.
I printed at 0.20 mm layer height with infill at 15%, 3 shells - you're results will vary. But there is enough flex (ABS) in my arms to keep it tight on the stand.

Basic edge cleanup and raft removal.
