Two-in-One Corner Trimmer for Bookbinding

This is a corner trimming jig for bookbinding that allows you to pick the two measurements you use the most and join them together to make a two-sided corner trimmer.

Trimming margins available: 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm. Each size is on a separate plate, just print the two plates you want and snap them together.

This is intended to make something that stays together permanently; the snaps can come back apart if you really work it but they're not designed for repeated use and will weaken if you do this.

I am a beginner at 3d modeling and made this as a learning project; I know there are already a lot of corner trimming jigs out there but I hope this twist will make it useful to some people. If you have any issues with the project or want to suggest any improvements, please let me know!
