I printed it in Overture Rock PLA, probably not water proof but may line it with something.
I Printed with Support, may or may not have been needed, just didn't want to print all that and have it fail. Use your own discretion, likely fine with no support on the corners ( block them out, center hole where tray pin goes needed support)
Bottom space for drainage stone.
80mmD x L200mm x H110mm
The author marked this model as their own original creation.
