This vat-draining funnel fits the bumps and bulges on a Nova3D Elfin"2" resin vat.

Stability is barely adequate when it's balanced on 500g hydrogen peroxide and resin bottles, so park it somewhere safe like in a plastic bucket.

I'd recommend sealing this print. There's something in UV resin that destroys ABS, polycarbonate, and probably other filaments. It makes them brittle and weak.

[Edit 4-29-21 I soaked some filament strands in clear UV resin for a few days. The ABS virtually melted. Polycarbonate seemed to bend more easily, but I'm not certain. Nylon showed no changes at all. So, friendly warning... Test your PLA, PETG or whatever before you print things that will come in contact with resin.]

Two of my trusty ABS build-plate scrapers first softened and then cracked after being wet with resin for a couple of days. A newly printed polycarbonate copy suffered likewise. I have some nylon filament soaking in a cup of resin as a test. Hopefully it is impervious.

To seal a print, I usually paint it with paraffin wax, and blow that around with a hair dryer. The liquid wax spreads and penetrates while any excess drips off.

Coating this funnel with UV resin might work. Paint it, and hit it with a curing lamp. I'm guessing cured resin would be an inert, protective shield...

If your software detects a teensy-weensy model, use the Metric file. (It's just scaled up by a factor of 25.4 because there are 25.4 mm to the inch.)

~60 grams ABS, 2hrs 30min. Printing it upside-down minimized support. Ymmv.
