Print Sloosher

I recently picked up a Sonic Mini 4k printer by Phrozen and completely forgot about the need to rinse resin prints in alcohol once they're done. Reasonably quickly designed in openSCAD this print sloosher is designed to fit in the following tupperware:
Sistema KLIP IT Food Storage Container with Clip, Blue, 1.9 Litre

If this isn't the size you're looking for then use the customisable version of this design here: https://www.thingiverse.com/thing:4704423

This shouldn't need any supports and can be printed as is.
