I printed with PLA at .32mm, 10% grid infill, Input Shaper, and my XL really struggled with the overhangs at the very top of each slot only to be saved by bridging. I might recommend adding adaptive layer heights and slowing down for those areas unless your printer is really dialed in for crazy overhangs.
(The entire model fits on the XL, I was just using up filament and ran out at the top)
The author remixed this model.
Cut model keeping it as parts, copied the top, and moved it straight up to match.
