This a template for easy customizable parchment holders similar to what is in Warhammer. 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.

Required:
4x m3 button screws at 8 or 10 mm length
4x m3 nuts
1x m4 35mm length screw + nut OR picatinny mount screw + nuts.

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.

Doesn't Matter

Yes

0.4 or higher

75%-100%

3 or more perimeters for strength. slightly higher than normal temp for better layer adhesion.
