This is a modular breadboarding table, designed as an affordable and customizable alternative to expensive optical breadboarding tables.

• The holes follow a standard 25 mm spacing, similar to many optical tables.
• Corner holes are sized to thread with M3 screws.
• Table holes are sized to thread with M6 screws.
• Connectors for each modular unit slide into the sides and are locked in place once the top plate is attached to the base, forming a three-part design that requires no supports to print.

Because of this connector system, the table is infinitely modular, letting you expand in any direction and build exactly the workspace you need.

I’ve started designing some components for this system and will continue to upload new ones as I create them. I’d love to see this grow into a community-driven project—so if you design your own parts, please tag them with “MOB” so we can all find and share them!
