The finished shelf unit used 16 tri-connector pieces, 12 duo-connector pieces, and 12 duo-connector pieces with wall mount holes. On one set of connectors, I customized the model to be closed (the original was opened).
This configuration used one sheet of 1/4" poplar plywood, size 24in x 24in. Each panel was cut to about 6in x 4in, and used the entire sheet of plywood, with no waste. I sanded the plywood panels, but left them unfinished because I liked the look.
The printed connectors friction-fitted very snuggly to the plywood. With all the pieces connected and mounted to the wall, I'm reasonably confident the shelf will hold together. I use it for storing/displaying balls of yarn, so there isn't much weight.
I made a second set of the same configuration for my son to hold small plushies. That one had connectors printed in green PLA and the panels were painted green. The paint added just enough width to the boards that I had to print the connectors slightly larger. This produced a loose fit and I had to secure the panels to the connectors with screws.
Overall, this was a great project and I really liked the design of the connectors. gpvillamil did a great job designing these.
MakerGeeks PLA, I think. PLA
The connectors printed really well, overall. I had some occasional problems with connectors lifting from the print bed (print bed is heated). I usually get this problem when printing too many pieces at one time.
- The printer settings makes me pick a model after the TAZ5 and the only option is Mini 2, which isn't the model I have. I have the full-sized TAZ 5 printer from Lulzbot.
