Metric Tap and Die Case for 12 Piece Irwin Hansen Metric Se

This is a remix of the wonderful [tap and die holder by Jimbo70](https://www.thingiverse.com/thing:2864503) When I printed his version, I found that the dimensional accuracy on my printer was terrible, causing the tray to sit very loose inside the case. I wanted the fit to be snug and easy to open and close, so I set out to design a minimal case that would use less plastic, be precise to my machine in order to create a press fit, and feature a hole in the back to help push the tray out. This design is not really an improvement, so much as a personal preference. It required some sanding of the tray in order to shore up the tolerances. If you're not sure if this will work for you, I recommend printing the tray first, then printing a "test copy" of my case and stopping it after layer 70 or so, and then testing the fit to the tray and adjusting the scale accordingly. I included the original .obj which can easily be tweaked in TinkerCad as well to preserve the uniform wall thickness. Print Remixed-Case.stl, and also print Tap-And-Die-Tray-Jimbo70.stl which is identical to the file in the link above. As an aside, I also reprinted the tray from Jimbo70's original design but scaled to better fit the dimensions of his case. While this worked, I was still not able to keep it snugly in the case. I ended up buying some [Grip Tape](https://smile.amazon.com/Non-Abrasive-Grip-Tape-CatTongue-Grips/dp/B08GG964P6) and sticking some small pieces to the bottom of the tray so that they slid in right as the tray was nearly closed. These created a perfect amount of friction to hold the case snugly in place. As a finishing touch, I sanded the guide rails down on the bottom side of the case so they wouldn't scrape off the rubber strips but rather guide them into place. Both methods worked perfect and now I have two functional cases, one for me and one for my dad, with barely any wasted prints.
