ESP8266/NodeMCU/Wemos dev breadboard

thingiverse

I was inspired by warwound's concept, but wanted to explore additional form factors. Here are eight and fifteen-row breadboard modules, along with every possible combination of an eight/ fifteen-row controller and eight/fifteen-row breadboard. Additionally, I discovered that the metal clips from a donor breadboard struggled to fit into the original eight-row breadboard module, so I thinned one wall by 0.4mm and now they slide in much more easily. I acknowledge this adjustment means the clip is slightly off-center, but I ensured the wall thickness remained a multiple of 0.4mm, allowing most printers to produce solid lines with one side being 0.8mm thick and the other 1.2mm thick. Surprisingly, it still grips the pin in the right spot. I found that using slip joint plumbers pliers allowed me to press the breadboard pieces into place while keeping them flat. The breadboard pieces may require some sanding to fit properly, but once they're pressed into place, they won't come apart and don't need any adhesive. The breadboard pieces were printed with the top surface facing down on the bed, enabling me to print without supports. UPDATE November 5, 2019: I realized that the original models didn't provide enough clearance for a press fit between the breadboard blocks and holders. To address this issue, I added 0.2mm on each side, allowing them to fit together seamlessly without requiring sanding. Furthermore, I needed a twenty-row breadboard for another project, so I've incorporated that as well.
