I was trying to use the flexible and small funnel that came with my GK3 Pro to filter resin back into the bottle, but it was much too small. The Uniformation Resin Bottle had a narrow opening so my usual funnels would fit. So I quickly designed a simple funnel that works with standard resin paper filters and has a spout sized perfectly for the Uniformation bottle.

Simply print upside down (as provided). No supports are needed.

Enjoy!
