I modeled this to use with resin printing. Though I optimized for a 0.6 mm nozzle, it should print fine with a standard 0.4 mm nozzle.

FEATURES:

• Neck of funnel has air gaps for easy draining and no pressure build up.

• Neck of funnel is wide for easy flow, but narrow enough to fit into most resin bottle sizes.

• Body of funnel is large enough to hold all of the resin from the reservoir.

• Removable filter cap creates a large surface area for faster filtration through a coffee filter.

• Design to be printed without supports (wide side down).
