This is a remix of How2Texan's Resin Print Dryer as I didn't have any mesh or grid to use for the original.

Using Tinkercad, I took the top part and added a solid face to it, and then in Cura I added a zone to allow changing the settings and removed the Top and Bottom layers. This allowed me to set my own "mesh" using the infill, changed it to 90 degrees and a grid pattern, and voila, instant print in place mesh.
