This is a model draining rack for the Saturn 4U.

The ones I found online weren’t very useful, so I made one from scratch.

When using it, the printer must be powered on; if it’s turned off, the filament tray will sink and won’t hold the filament in place.

The two outer holes are for use when the build plate is laid horizontally, while the inner holes are designed for vertical orientation.

You must tighten the screws before use; otherwise the entire assembly will tip over
