El Cheapo O2 Purity Tester build kit face plate

Face plate to use with El Cheapo II DIY O2 analyzer kit from OxyCheq.com for DIY oxygen generation systems for glassblowers. Fits perfectly into the back of the box provided, fits all of the components nicely in an easy to use orientation and saves the trouble of carving holes out inaccurately and messily with a dremel and exacto knife. I suggest printing at a fairly high resolution, I used 0.2mm layer height and printed in Atomic PLA clear face down without any supports. You will have to use a thumb tack or a tiny drill to open up the holes in the tops of the posts that the 4 screws go into to hold the box together. I suggest printing at as low a temp as you can get away with, at least for the last 10 layers so that the little male ribs that go into the female slots on the provided box don't end up with a lump at each end that needs to be filed down to fit the rib into the corresponding slot properly.
