Need Advice Please

Hi Guys

still looking for help

Hi everyone,


I’m looking for some guidance on designing or sourcing a enclosure for a Teensy 4.0 lockable

My initial thought was to go 3D-printed, but a lot of the examples
I’ve seen don’t look very polished or durable.

( I PRINTED A FEW LIKE A CLAMSHELL BUT THEY DON"T STAY TOGETHER TO WELL )

I reached out to Polycase, but unfortunately they don’t do true custom enclosures.

(I CALLED A FEW injection mold companies, but they want way tooooo MUCH for the mold )

Ideally, I’d love something that looks clean and professional possibly a metal enclosure or maybe a liquid resin printed


Has anyone here:

• Designed a clean, professional case for a Teensy? any Model ???
• Used aluminum or steel enclosures successfully? how do you all mount it in the case
• Found a manufacturer that does small-batch custom or semi-custom cases?
• Solved locking/tamper-resistant designs in a clean way?

Any suggestions, examples, vendors, or “don’t do this” lessons would be hugely appreciated. I’m open to hybrid ideas too (metal shell + internal printed frame, etc.).


Thanks in advance — really appreciate any direction you can point me in. also
