When printing with resin, too much infill is a recipe for disaster. Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Note that both hollowing and hole-drilling are computationally expensive tasks and will take some time, especially with complex models. It does depend on the dimensions of the print itself. Since I am printing them upside down and the bottom of the barrel is touching the build platform I guess I would need to add a 3mm hole in the side of the barrel near the bottom and then one in the lid. Reddit and its partners use cookies and similar technologies to provide you with a better experience.
