This is a fully printable resin vat draining rack with height-adjustable vat holder and funnel systems. To adjust, loosen the lock bolt, slide the funnel or holder to the desired height, and re-tighten the lock bolt. The rack grooves mate with half-cylinders inside the vat holder (see CAD cross-section photo) when the locking bolt is tightened down, so there is no sliding once the weight of the vat is present. The holder is angled forward by 5 degrees to prevent resin from dribbling under the corner of the vat. The angle also maximizes stability by moving the center of gravity forward. This is very stable even when adjusted to the maximum height!

The funnel is a separate item from the "car" it rides in. The ring in which the funnel sits is open on the end to aid in putting it in/out when the funnel is raised up close to the vat. There is a template that allows you to slide standard paint filters inside it, to aid in cutting them down the right size/shape to fit the funnel - very handy!
