To print these, stand them up on the “back” of them (where the flat bit is) and have supports running up them where the letters are. I heavily recommend tree support.
Be careful when removing the supports, as the “a” letter is fragile.
To install, start by removing the original plates (you must open the blaster and unclip both sides to do so). Then I recommend scuffing the inside of the printed plate and the outside of the blaster where the plate would go. Then use some gel-like or more viscous super glue and hold the printed plate in place while it sets/cures.
These are not as durable as the original plates, but that is a side effect of how the parts are made and the print orientation that yields smooth surfaces when seen by people. These parts are also not a 1-to-1 copy of the original, as that would require 2x the amount of prototypes needed. I am happy with where these are.
There will not be a clip version as they wouldn't print properly.
The author marked this model as their own original creation.
