I need opinions on improving my nice ABS enclosure.

HKPhysicist

Dear Engineers and Experts,  Blush

I have found a very nice enclosure to contain my air monitor and sensors.

The only drawback of it is - there is a large opening (perhaps for ethernet) which is redundant for my design.

So, could you suggest a way to cover or patch this rectangular hole (inside the blue lines) so my end-users cannot see or touch the electronics inside?

The manufacturer claims that this enclosure is made from ABS plastic.

Tooling I have - a Bosch Dremel 3000 mini drill with wheel cutters, a mini table vice.  Wink

    Low volume production? Design a PCB to cover all those unused holes in one go, and get it made at say 0.8 mm thickness and glue it on. You don't need any of those tools you mentioned.

    Hobby use? Do the same with thin plastic sheet (e.g. a cheap plastic document wallet, doesn't matter if it's flexible) and hand-trim with scissors and glue it on.

    Yes, it is for low volume production.  I have designed 3 PCB layouts for other 3 enclosures with Kicad v10.  Only this one has the extra rectangular hole.

    I need the USB-C opening, switch button hole and the light hole.

    The main PCB is horizontal to the enclosure bottom.  According to your suggestion, how do I get a PCB which is also vertical?  Neutral face

    Not sure what you mean, but I think PCB covers, keystone covers, 3D printed covers mentioned by all, are all viable options to meet the requirement to cover/patch the cutout.

    Shabaz means to use a separate PCB as a cover for the hole, not to use the main PCB to cover the hole.

    Another option might be to apply tape over one side of the hole and then pour resin from the other side to fill the hole. Once set, remove the tape. You can colour the resin to match the colour of the case before pouring.

     Another option might be to get some thick self-adhesive labels printed and stick them over the hole. You could make this label larger so as to cover the whole end so as to provide meaningful and neat labelling for the holes you are using and cover the ones you aren't.
