Creativity takes time. Rome wasn't built in a day.

You can 3D print cases for a while. Injection molding dies can get $$$. You may be able to work with a local injection molding shop and just make your own (limited run) aluminum die set and have them mold the parts for you. Aluminum dies don't last as long as steel dies but they are far cheaper to make. You might even get lucky and find that they already have some old abandoned dies to make a suitable case.
BTW- For plastic parts straight sides are a no-no, they tend to stick in the mold.

I learned at wheelen engineering when designing a mold use 2DEG at least on sides so ejection pins can push the part out it is tricky to make a good mold there is also polyject I can go to and get old molds as they can't get rid of them steel is not worth much so they sit and rust. I may just print cases the hard part is I will have to use ABS and ensure a good seal I dont think they should be epoxy filed so they can be repaired easy not so much throw away. The PLA I use for my printer is water soluble so it desolves lol.

2° is good 3-4° is better.
Epoxy can be removed with a heated solvent that is very dangerous.
I figured to go with ABS initially then try some PETG, ASA, nylon, and TPU. Some of them require high printer temps. High air temps also help but that is hell on electronics so I am still looking at printers. I have a perfect place to use a printer, right on top of the kitchen stove since there is a built in vent hood.

Lol I like it stove top 3D printing.
I have started my second 11hr print since yesterday making machine parts I can't wait until all is done.
