Creating enclosure for electronic appliance

[treviko]

I'm going to create electronic enclosure for custom project, two small PCBs mounted in one case. Design for 3D Printing.
Large PCB have 4 mounting holes, small PCB 2 holes. I'm not sure how to properly to attach PCBs inside enclosure. Should these holes be used to screw the PCB to bottom base with self-tapping screws, or for positioning the PCB using round pins something like this? Tne PCBs are thin (1.3mm), and I'm worried that the PCB does not bend when use self-tapping screws. Another point is, how to attach together top and bottom parts of enclosure?

I use threaded stand-offs with suitable screws on top and bottom end of the stand offs.
You can also get plastic clip-ins that have no threads.
Max.

for joining two parts of enclosure, or mounting PCB inside enclosure?

hi

Take a look at the enclosures offered from Hammond. Some of them already have mounting standoffs for a PCB and are low cost. It’s best, however, to take the enclosure form factor into account before designing the PCB.

If you are 3D printing, use the advantages of 3D printing...

Use captive nuts. Super easy - I highly recommend.

CAPTIVE NUTS AND MORE IN 3D PRINTING

CAPTIVE NUTS AND MORE IN 3D PRINTING: Embedding metal object inside 3D Printed parts is certainly a practice that solve several assembly problems and achieve an higher performance level of our printed objects in terms of: ease of use, clean look as well as higher strength to mechanical …

Good assortment. But in my case I have to use custom made enclosure,as I have pre-made PCB (mount two PCBs in one enclosure).

It should not be hard to use this box as a starting place. Make it bigger. Put a screw in every corner. Add standoffs to match your two boards.

Here is a idea. Put one board in the box and the other on the lid.
