Tower PC blind plates to cover empty drive slots

When printed from PETG on a Prusa i3 Mk3S, these plates fit perfectly into the front of my tower PC to cover the empty drive slots. 

The snap hooks work nicely to hold the plates in place with no rattling. I have not tested if PLA is flexible enough to work as well, let me know if you should try. Since PETG is typically shrinking around 0.2% to 0.4%, you may end up with slightly too large plate if you print this in PLA. In that case you may want to print them scaled to 99.6% size.
