I hollowed out the original model by LSMiniatures and added drainage holes.
Print this file on an SLA printer, using only 1/10 the resin as the solid model. I put the support trees on the inside in my slicer since you wouldn't see them anyways.
Nearly no post-processing besides the UV cure.

The .form file is a ready-to-print file on the Form2 in white resin. It 's at max size for the printer and uses around 185 mL of resin over 22 hours at 50 microns resolution.

I'm sure you could print this file on an FDM printer but since you could just lower the infill percentage it would probably make more sense to use the original file.
