Wooden triangle shelves - invisible connection no glue

Hi there!

I designed a few cool triangle shelves for a furniture company.
Although I found some DIY instructions on the net, I did not found the one that suits me.

All of the DIY instructions either glue it, or use bolts on the end side.
However, for the furniture company it is important that the connection is invisible, the customer needs to build it himself, and no glue can be used.

Do you guys know any method? An Ikea male and female kinda like is not working here because of the corner.

Thanks a lot in advance!
Kind regards,
Stephen Lammens

Tennon and mortise or dove tail joints but would still need some glue, metal brackets but they will need screws.

I went with about 48 feet of Gorilla Rack ( it may have a different name now) fro Menards. It’s adjustable and looks good if you buy the door kits.

The shop came with about 32’ of painted wood shelves, and I made some more with scrap I had laying around. Cheap, but not adjustable, and I really need to ad some doors to reduce the cluttered look.

A single large dovetail comes to mind but if the angles were cut to allow all 3 sides to slip together at once, it would also fall apart in use.

Traditional Japanese joinery would probably have a solution but I can't advise.

Why no glue? I've bought knock-down furniture that came with a small bottle of white glue...

On further thought I think the answer may be a double-dovetail key that would join the 3 corners. The dovetail slots would have to be accurately milled into the adjoining faces of each joint for it to work & look good. Are these going to be mass-produced in a factory?

Made from a contrasting wood (or plastic) it could even be a nice design detail.

I'll look for a picture...

Sorry for posting separately like this but since the recent forum change I can't edit my own posts any more.
