I am designing a small and compact measurement device housing an arduino and breadboard.

I have a number of small electronic PCB's and components I would like to house securely inside and I was wondering if people can recommend ways to secure them so they don't rattle about inside.

The case is made from plastic and 3D printed.

I want the components to be removable in the case of fault or replacing, so I was considering velcro as an option.

Any better ideas would be much appreciated.

  • \$\begingroup\$ I've thought about nylon screws, however I want the device to be compact so the base is filled with the arduino and breadboard and remaining space on the side walls hence why I was thinking to velcro strap it inside. I suppose nylon screws could work, but I just don't really want bits sticking out/inside the finished product. \$\endgroup\$ – Adam Jan 30 '17 at 21:52

If you have a 3D printed box I suggest that you re-design the 3D data set to include printed in standoffs on the inside of the box that match the board mounting holes. These standoffs can be designed with a center hole in them so that you can mount your boards with short self taping screws.

Such standoffs would look similar to this one from a standard molded plastic enclosure.

After all, 3D printing is all about customization - make use of it.

Anything really. Most of the time it amounts to including a hole in the board.

Technically double sided sticky tape and velcro are not ESD safe and should not be used in a real design, but if your a hobbyist it probably wouldn't matter.

Some things that I've used:

Zip ties - Just measure the zip tie and put a hole of appropriate size in the board

Standoffs and mechanical fasteners enter image description here
