Funnel for Sunlu Resin Bottles & Coupler

This model has only been tested with the flat Sunlu resin bottles as displayed in the included photos. Hope you find it useful and please upload your makes! :D
 
No Supports should be needed when printing in the tip up orientation. No supports are needed for the couplers either as long as they are printed with the flow direction arrows facing up.

EDIT:  I have made some changes to the coupler.  I made the internal spout much thicker and gave it a spot/tip to drip.  There are now TWO versions.  One with vents, and one without vents, enjoy :)

For the idea of making a coupler to connect two bottles and allow one bottle to drain into another.  Print orientation of the couple is important.  Orientation should be correct as soon as you bring it into the slicer.  Just in case it isn't, make sure the text is upside down.

For the idea of adding the ribs to the funnel :)

EDIT: I did yet another thing…, I added a lot of variations.  I know I can't please everyone, but here we are, haha. Enjoy :)
