Breadboard Base Project

Here is a 3D printed base for three MB-102 type breadboards (from Aliexpress).

I designed it using Tinkercad.

Print the base, face down. It measures approx. 20 x 18cm and can take about 15 hours with 15% infill at 0.2mm resolution if using an Ender 3 or similar printer.
(no supports are needed)

Instructions for the wiring etc. are on my website .
