This is a fully functional 3D-printed breadboard.
It comes in two pieces: the main body and the bottom cover.
It gives your projects unlimited size and flexibility.

✂️✂️✂️

Cut small rectangles from aluminum foil.
Each piece should be 1.2 cm wide and 2 cm long.
Fold each piece twice along the 2 cm side, so it becomes about 1.2 cm × 0.5 cm.
Then gently tuck the folded foil into the small gaps between each breadboard row.

Make sure the foil pieces do not touch each other, or you will cause a short circuit 💥💥💥.
After filling all the gaps, snap the base part

 onto the main body, and you’re good to go.
