Since the old covers for the nameplates of our mailboxes held partly only with tape. There I want to change them to new ones.
The original ones from the manufacturer of our old letterboxes were very expensive that I created this template myself.
Since I was unsure if I could handle transparent filament good enought, I made a cutout for an acrylic glass insert.
For the glass I simply took an old unscratched CD cover and cut it to size.
(There exists a lot of tutorials how to cut thin plexiglas…)
The cutout is optional and can be removed via checkbox (for all who are confident to print it so clear - for example with a resin printer...)
All parameters are controllable and can be adjusted individually to the existing cutout. Therefore, the model is not only suitable for letterboxes but for all square cutouts.
The author hasn't provided the model origin yet.
