This tool/template is meant to be used to cut a standard A4 printer paper into and envelope that fits an A5 letter folded in half.
The template has slits for a toothpick or sharp tool to cut/mark the folds.
The final size of the envelope is 150mm by 110mm (approximately 5.9″ by 4.3″) with fits perfectly a letter written in A5 paper after folded in half.
I plan to make the template foldable with print in place hinges in a future version, but it suits the purpose right now, I hope you like it and find it as useful as I do.
The model is pretty simple and should be printable in any material or setting as long as it fits in your print bed.
The author marked this model as their own original creation.
