Raspberry Pi Case

Well, how you should proceed depends on your printer. When I designed this, I was using a higher end 3D printer which uses a soluble support material, which is dissolved after the print is done. That way having overhangs isn't a problem.
However, most hobby printers don't have that option. To get around that, if you were so inclined, your best option would be to modify the models and add some support columns underneath. How many you need and what width will depend on your specific printer. Ideally you'll want to design them so that they can be snapped off easily.
I hope that was of some help! Sorry the design isn't more hobby printer friendly, when I originally made it I was just intending it for my own personal use, then just kind of posted it here on a whim. Good luck!
How do you print the outer case file with the floating base? the supports dont seem to work, about to try with the raft option selected. But any insight here would help. Maybe revise the intructions as well since this isnt intuitive either.?
This was designed for 3D printing, so the design would need to be modified to be able to be laser cut. And, of course, the round edges aren't possible with a laser, but you could sand them afterwards.
If you want to modify the design, I'd recommend splitting the "outer" case into 3 parts (sides and bottom). Then make the "inner" case into a flat pattern. Then you can cut it from acrylic and heat and bend the acrylic after it's cut.
If you do that, post up a remix, I'd love to see it!

Per request, I have uploaded STL files that are drastically smaller. They're technically "rougher", but for 3D printing you probably won't notice a difference. Use the files marked "1-25 Rough" (in either mm or inches) if you want to 3D print them. And use the files marked "1-24" if you want to work with the STL files.
It's been brought to my attention that the STL files I've uploaded may be scaled improperly. I've noticed Solidworks often has issues when saving metric STL files. So, I'm leaving the original STL files, but I'm also uploading two sets of new STL files. The first set (with the suffix "1-24") was saved in millimeters. The second set (with the suffix "1-24 Inches") was saved in inches. If the mm version doesn't work, give the inches version a try, as Solidworks seems to be better about saving STL files that way.
Print the two pieces (Inner Case and Outer Case), and see if it fits your Raspberry Pi. You might need to do some light sanding or filing to make it fit (I didn't give it much clearance).
To make it look pretty, sand the outside of each piece smooth (avoid mating surfaces), prime, and paint.
