Thinner Fan Guard for Prusa i3 MK3s+

This is a very lightly modified version of J White's excellent fan guard (which is a remix of Der Peiner's). For whatever reason, I did not have enough room on my printer for their model. The printer was detecting crashes and too short of an X axis. As a result, I made a slightly thinner version. If, after printing their more elegant model (it has chamfering and mine doesn't… i can barely spell chamfer) you find that it is too thick for your printer, try this one out. No support needed, I went with .15 layer height in when I sliced. It's a quick print. I strongly recommend printing in PETG, since it will be so close to heat.
