Just another build plate stand for up to ten build plates. It's designed for Creality K1C plates but could be used for all plates that fit into a 5 mm slot and wouldn't drop out of a slot length of 16.5 mm.
No support needed, no special requirements. But it might take a while (with Hyper PLA and 0.20 mm it took about 10 hours, 420 g filament).
