Resin print washing trays 100mm w. minimum support waste

Wanted to turn two old plastic containers into IPA washing stages on a magnet stirrer, therefor I needed a basket to give space for the magnet stirrer.

But basket designs tend to need either a hilarious amount of support material or a part orientation, which won't work for one-shot printing on SLA printers (high risk of failed prints).

I therefor tried to design it in a way, that (on a resin printer) the amount of needed support material is minimized. To achieve this goal, orient the part on the SLA build plate in such way, that the longer diagonals of the rectangular cutouts are aligned vertically (see pictures).

• Round: ~32g resin for the part + ~8g in supports (medium standard supports from PhotonWorkshop 4)

• Square ~44g resin for the part + ~9g in supports (medium standard supports from PhotonWorkshop 4)

• Print time ~4h @ 2.0s/50μm on Photon Mono M7 Pro

As it's not a decorative part and tolerances don't really matter, I believe it does not require specific printer settings for this part & SLA printers. Just follow the recommendations of your resin manufacturer, your resin calibration results and your experience. 

Just one thought --> use a resin which is resistant to your cleaning solution after curing (not sure whether using a water washable resin would withstand continuous IPA exposure too well). To be honest, I don't know that of my resins either, I simply don't find any datasheets which would answer such questions. 

For FDM printing I can't give any advice on placement/orientation/supports as I don't owe one yet.
