Perpendicular Join with Acrylic Screw and Spring Pins

Here is an example of fastening parts in a perpendicular join with a common acrylic screw. Also shows joining layers together with a spring pin. You should be able to assemble any structure you need with these two techniques. Layers create a countersink for the screw head.

I’ve worked up a dozen or so other techniques for joining parts together (custom 3D printed clips, etc) but this is lowest cost and the strongest technique out of the set. No glue required.

Oh cool I’d never seen acrylic screws.

@pubultrastar I bet these might be a cool variant in your geometric builds.

Very interesting! It does look quite sturdy. A useful technique beyond acrylic, too.
