Pen stand for the Huion PW100 (H640P, H950P, H1060P, H1161, H610 Pro V2, HS64, HS610, Inspiroy Ink H320M).
Print each piece with it's largest face on the bed (as shown in slicer screenshots). I printed at 0.08mm for higher quality threads, but I'm sure it would work fine at larger layer heights too.
