Customizable Paper Holder Magnet Bar

Based on an idea presented in the "Moai Laser SLA 3D Printer Owners" Facebook group by Nils Fromm to hold a paper towel in front of the resin tray to catch drips, and a design by Caladonis.

You can customize this for different lengths, magnet count, magnet shape, etc.

You probably need at least 25% infill.

Whether you need supports or not depends on your printer.

The magnet holes may require glue, or be just a press fit depending on the accuracy of your printer.
