This is a remix of my the purity seal and my picatinny template where I have the what I have adopted as the equation to the purpose of life. It is religous in context. It EttE bracketed to form part of an equation. E(ndure) t(o) t(he) E(nd). The two t's form a pi symbol to represent eternity and the the last E is turned inward to represent our death looks towards eternity and so forth. It has significant personal and family sentiment as my father endured extreme pain all his life, developed cancer, and eventual passed but not before spitting in the face of death and lasting far longer than anyone believed he would last with brain, lung, and skin cancer, a brain hemorrhage, and many things he had already been afflicted with.
Instead of the original which this is remixed from, this is not held together using glue but rather screws and nuts. You can hole punch the paper after weather proofing it in some way in order to fit between the plate and the mount. You can print in PLA if this is for airsoft, but on my real gun this will be ABS. Nylon with an additive or PETG will work fine too, just avoid soft and low glass temps. Add glue to the screws if they wobble or come loose.
4x m3 button screws at 8 or 10 mm length
4x m3 nuts
1x m4 35mm length screw + nut OR picatinny mount screw +nut
EDIT 8/28: What I learned from printing: 3 or 4 perimeters are required to get a smooth finish on lettering (unless you have some really nice slicer engine, I used matterslicer). Don't mount anything on metal furniture unless they have some form of insulator between them and the barrel/chamber or they will reach glass transition point and melt (this only applies to standard filaments and not high temp filament).
Also dont make the engraving too deep or it will look bad.
any PLA, ABS & PETG
3 perimeters or more and higher temp for strength
