Heres my design of stand-alone moon hexagon piece display.
While printing put it on its legs. I used supports, hovewer you might try without if you're brave enough ;)
Defined tolerance 0.2mm between the insert and piece, which works very well with my prusa usually.
with 0,6mm nozzle, 0.3mm layer height and supports it took around 8h to print.
The author remixed this model.
I'm just a staaaaaaand….
