Form 1/Form 1+ Etching Vat

This file is for a vat that is meant to be used for etching or protection of the printer when there is no actual vat installed.  I have been playing around with the idea of etching pictures and etching PCBs with my Form 1+.    I also wanted to have a vat that protected the Form 1+'s main mirror without leaving a vat filled with resin or keeping around an old used vat.   I drew this vat and printed it out on my ROBO 3D to solve both requirements.  

After printing, I used .093" Polycarbonate for the window.   I used some SUN ART Paper to "etch" my first picture, which came out as expected.
