PCB Prototyping Breadboard Mounts – 30mm, 40mm, 50mm

Modular mounting brackets designed to securely hold standard breadboards and small PCB prototypes inside enclosures or on flat panels. Ideal for electronics projects, control boxes, and low-voltage installations.

I STRONGLY RECOMMEND HAND TIGHTENING AND TRUSS HEAD OR WASHER HEAD TO MOUNT TO A WALL. I DID NOT PLACE A COUNTER SINK.

WHEN MOUNTING BOARD TO ENCLOSURE, USE M2X2MM - M2X6MM AND HAND TIGHTEN.

These mounts provide:

Stable support without flexing

Clean cable routing space underneath. make taller for more room.

Reduced stress on solder joints and components

Easy installation with standard screws

Sizes included: 30mm, 40mm, and 50mm variants to fit different board lengths and enclosure layouts.

For best results:

PLA works for quick prototypes

PETG recommended for durability

PETG-GF (glass fiber) recommended for electrical enclosures due to added rigidity and thermal stability. I included the 3mf for the glass fiber versions.

Make taller if you need to use screws longer than 6mm or they will break through the bottom.
