Description
This is an all-metal design for a RepRap frame that I came up with while on vacation in Puerto Rico. Resources on the island are very limited, but I did find the local Home Depot around the corner, and there was a stash of tools, including a drill and hack saw, in one of the closets of the apartment we rented.
Jibaro is a word that refers to some of the island's rural inhabitants. They tend to grow their own food, and raise chickens and hogs. They are very resourceful, and creative. Many of the craftsmen might be considered jibaros.

The angles are 90, 90, 150, 150, 90, and 90.
You found a Home Depot in one of the closets of the apartment that you rented?! That must have been a huge apartment! =-)
Seriously, though... Anything that reduces the reliance on pre-printed parts is great.
Awesome, can't wait to see it finished. Where in the island were you staying? [jib == jibaro :)]

Instructions
Note: There is a new "compatible" vertex which uses a shorter length of bar. It's closer to the size of the regular Mendel vertex.
I did not have time to complete the frame while on the island, but I do intend on continuing this design, at least for now.
To construct the vertex part (you will need 6 of these), begin by using a hack saw to cut a 5.25" length of punched bar. The ends of the bar should begin at the center of a hole. If this is not the case, make it so, otherwise the holes will not be in the right positions.
In this piece, you are then going to saw six (6) slots into the metal, about half way through. These will become your bend points.
From the outside in, the distances are 0.375", 0.75", and 1.875" on both ends.
The four bends closest to the ends are 90 degrees, and the two (2) innermost bends, are 150 degrees. This is consistent with the regular RepRap Mendel-type machines.
Use pliers to bend at the marks. Once you have three of these vetexes bent, you can place them end to end to check the 150 degree angles. They should be flush against each other. Adjust if necessary.
