Designed to hold 8 tablets. The individual slots are measured to hold a tablet that is no more than 22.5 mm thick when a protective case is added. The overall surface area of the print is 273mm x 144mm. I ended up shrinking the final version down in the Z direction when slicing (set at 70%). Tested it out and the reduced height works great and saved some filament.

Print time is roughly 17 hours, running at roughly 70 mm on average

No supports needed, but a brim would be suggested if you have the plate space to reduce warpage for something this long (raft would work too if you don't mind using more filament).
