This is just a stand to hold up to 10 engravable acrylic plates. At 100% scale, the slots measure 76mm x 2mm.
Scale how you want.
I printed at 0.3mm layer height, and it looks meh (see photos), but it's utilitarian for me so I'm shooting for a shorter print time. If you care about it looking smooth, go way down to 0.15 or 0.1.
Low infill ~15%
No supports
It has a big flat footprint, so you may want a brim to stop it from shrinking away from the bed.
