I have not built a pyramid yet but building the field elements the past many years leads me to one idea. Just for in school testing, not pre-contest event.

Making just one side not four.

Determine the width of the top (90 inch high) bar. Say it is 24 inches for example ( I have not done it yet). Make all 3 pipes, 30, 60 & 90 just the 24 inches wide. I would build it with 2 x 4s or 2 x 6s and the metal pipe. So the wood acts like stair stringers. Hole saw cuts a circle in the wood to slide the pipe through. Fastener to keep the pipe from spinning.

On a future game note, unless your robot can adjust left and right on the way up, you better start "perfectly" centered on the 30 inch tall pipe.

IF I CAD one up in SolidWorks I could share the drawings but it is not our top priority this week.

Good Luck!
