Dovetail cutting jig
thingiverse
Dovetail joints are one of the strongest methods for joining 2 boards at a 90deg angle. You can use this jig as a guide for cuts either by hand or using a band saw. I've included 6mm holes for adding magnets to help keep the jig and/or hand saw stable. If you need to cut a TON of dovetails, then a router+template is definitely faster. But for the amateur woodworkers looking for a small challenge, this should help give you a win. This is a work in progress, but I'm uploading it now as a way to document my work.
