This set of breadboards is perfect for custom projects that require mounting and adjusting the position of various elements!

The pitch of the breadboard is 5mm and it is ready for M3 screws without additional nuts (holes are 2.95mm and hold screws well). In pictures you can find drawing with all sizes.

The breadboards can also be joined together both horizontally and vertically.

There are several sizes available (all 15mm high):

• 110x55 (basic)
• 110x105
• 205x110
• 215x205
• 305x215
• 320x305

A similar design with a much larger pitch and screw size is used as an optical breadboard in science. This one is designed to be good for less precise research. Also fusion files are attached if you feel need to edit it.

I've developed the design during some tests of my research and as it's very handy, I hope you'll like it too!
