I recently got a bunch of aluminium extrusion so that I can rebuild the Turquoisebot in a more accessible way.
I’ve used OpenBeam before, but not 8020 style extrusion. As a quick test project, I decided to make a standing desk addon for my work table.
“Before you cut firewood, sharpen the axe.”
I noticed the metal bandsaw was cutting atrociously, so I spent an hour re-aligning it & testing out the tension and perpendicularity.
Not perfect, but at least the right angle joints didn’t fail the laugh test when I put them together.
Some assembly later:
It should be at the right height to have my elbows perpendicular while standing & using the keyboard.
As a construction method, I’m amazingly happy with it. I have an extremely sturdy frame, and it was very quick to put together. Moreover, if I change my mind in the future I can reuse all the parts easily.
