After having done the hollowing process, we must make different drainage holes for the leftover resin. Ive heard of some people actually drilling their own holes in a model using a handheld drill, but you definitely want to be careful doing something like this. Each hole is always perpendicular to the surface and its diameter and depth can be configured - the current settings will be used for newly placed holes. A trade-off between accuracy and performance.

Further listening (especially for larger prints) is here from Angus/Maker Muse, who shows a way to hollow out with a hollow base but skipped the drain vent, and Mark Rhodes, who prefers to use 5mm holes where possible. You can fill hollow resin prints by using products like expanding foam, epoxy resin, or even fine grain silica sand. Fine grain silica sand, then seal up the hole with a few drops of resin on the print, then cure it with a UV light to harden it. You can orient it identically to your preset in PreForm, if it makes it easier to find the correct location for the vent holes (Edit > Transform).
