Domino "Tenso" Connectors?

[onocoffee]

I came across this as I was perusing 3D files. They're called "Locking Domino" and seem to be remotely similar in use to the Lamello Tenso (maybe?). Meant to fit 8mm mortises at 15mm deep.

I printed a few to see what they are like. Seems interesting and wondering if anyone has used these in any application. The author says they're "great for fastening cabinet face frames or removable panels." Thoughts?

Are you referring to this (the latest version is 1.1 for 6 and 8mm mortises )?

This looks to be the same. I found the file here:

Download this free 3D print file designed by Oni. Locking tenon for Festool domino style mortises. Fits 8mm mortises that are 15mm deep. Great for fastening cabinet face frames or removable panels. These can be fastened with wood glue, super glue, or screws if you like. I was able to use an 8 X...

Thanks!

EDIT - After watching the video, they do look a bit different. The version in the video has thicker depth pieces than the 3D version.

Very interesting, needing to screw them in is a bit of a drawback in some situations, but they're certainly a clever design.

Given you need to screw them in to stop them simply coming loose, I don't see how they would work well for face frames unless the frames were sufficiently thick enough to allow for the screw in addition to the tenon.

They definitely aren't comparable to Tenso's for thinner materials for this reason. The beauty of the Lamello connectors is the groove the fins on the connector slide into that make it impossible for the connector to come loose.

This also allows Lamello connectors to work in boards down to 11mm thick.

Although thinking about it, these do lend themselves to being offset so I don't see why you couldn't set the face frame side to 5mm deep, and use a 13mm or so screw to hold it in, and then set the other half 25mm deep.

So yeah, if you offset them, they could be very useful indeed.

Jonas Winkler did a poor review of those click-lock tenons.

• Complained too long about shipping costs
• Did not read the instructions nor watch the original maker’s video
• Used a metal hammer on elastic plastic parts
• Unnecessarily beat on those same elastic plastic parts
• Ignored the change in geometry when driving the screws into the piece

What Jonas could have done better:

• Read the instructions and watch the original video
• Used a Domino tenon to push BOTH mating pieces into the mortises
• Used several wood tenons for alignment and stiffening
• Learn how to screw in the plastic tenons without any deformation
• Show a real-world usage of those click-lock tenons
