Wait, I think I missed a space in there…

Good advice, Hillary!

Oh, wait, you meant the other guy.

By the way, I printed a full-sized ABLE corner connector, just to have a model to work with for designing smaller connectors in OpenSCAD. It’s a really well-thought-out system, but the fundamental problem is that making his sample table would require five days of continuous printing and more than an entire spool of filament. Ugly metal connectors at Home Depot are faster, cheaper, sturdier, and paintable.

For the tinkertoy-takadai, I’ve decided to simplify and just use 3D-printed T connectors so I’ve got wood against wood, with the plastic keeping things aligned. I can actually just replace the pins on top of my monorail koma design with an open cube to form the T; I know this prints quickly and cheaply (although I’ll do these at 100% infill for strength).

While those are printing, I’m going to lay out the arms on the floor to set the width, calculate the minimum required height from that, and the rest of the numbers fall out of the design I did three years ago. If I’m ambitious on Saturday, I could have it ready for a test braid.
