I love these projects but when I have had a need for a display at home, I struggled to find a case! Small displays complete with a case, that was also slim and of decent material, seemed incredibly elusive. I suppose the modern workflow is to 3d print one: but perhaps other consumers, like me, buying a $20 SBC and a $20 display have not outlayed for a 3d printer... Or purchase a 3d printed one to spec? Unfortunately I don't yet have the confidence in the quality of materials of a purchased 3d printed item, nor enough familiarity with the materials and process to choose from the many options online. They also did not seem particularly cheap. Most recently, I ended up finding a 2nd hand (refurbished) small tablet, and simply used that as the display for a small system. It pulls the display content over wifi and displays it in a browser, which is incredible overhead for such simple content. But it is slim, has a touch screen, comes complete in a case, and was cheaper than purchasing a similar waveshare or other unnamed-brand display with a matching case (where one could even be found!)

  Precisely this. Or try making friends with someone with a 3D printer or ten. I generally print and send small things for free, for anyone who asks nicely in certain forums and discord servers so long as they're local (country) or want to pay the shipping. 3D printing is a hobby for me, I use it for functional prints mostly, and I love for people to experience what I did the first time I got my hands on something 3D printed. I used 3D print services at first, but I found the quality from some of them wasn't up to my standards; they're optimising for speed and profit, fair enough.

    Do you happen to have any suggestions as to how to get started with 3D printing? Can you recommend a 3D printer to buy as the first one?

      If you have money and little time and patience, Bambu labs p1 or x1 series is one of the easiest to set up out of the box, and you can get or add on the AMS (automatic material system) which makes it easier to do multicolor printing. (US $700+) If you have little money and more time and patience, Creality Enders are a good basic introduction to all the nuances, pains and heartaches of 3d printing but will give you a better idea of fundamentals. ($100-300) Expect to lay out another $100 for filament, upgraded bed and other small parts like bed springs. Don't buy a used machine as a starter because you'll just be taking on someone else's headache, but once experienced you can find some craigslist and offerup deals for spare parts or a small print farm, occasional like new "used twice" $50 printers.

      If you have the option near you, definitely search for and visit a makerspace near you. One reason is that 3D printers require frequent maintenance - something which will be "taken care of" at a makerspace - and you can spend time talking to 3D experts before making the commitment.

      To get started, buy a printer. If I was starting over, I would get a BambuLab A1 https://bambulab.com/en-gb/a1 https://bambulab.com/en-gb/a1 If you want to spend less, you can get an Ender 3 or one of its many clones https://www.creality.com/products/ender-3-3d-printer https://www.creality.com/products/ender-3-3d-printer I advise against self-assembly. Especially for your first one, let the factory assemble it. Doing it yourself significantly increases the likelihood of alignment/calibration problems. These will be frustrating and hard to chase down, especially if you don’t have a mechanical background. You can make a whole hobby out of building, modifying and upgrading 3d printers… but that’s a very different thing from using a 3d printer as a tool for other projects.

  That's an incredible idea -- I should chase down the 3 or 4 libraries near me and see if they have a 3d printer. If they have one, the staff there are probably quite keen for visitors to print a file. I do wonder about longer prints and how that might go, but that's a problem for another day. Re: 3d printing as a service, when I googled it here in Australia it was plentiful, expensive, and mostly focused on higher quality materials - for prototyping serious gadgets, it seemed. There were generic websites that seemed to be based overseas, but the options (and therefore my guess at quality) were behind a wall of lingo and technologies. I would have needed several hours I think to google, ask LLMs, etc, before understanding which to choose. And then? They were still not particularly cheap -- I expected to spend less on the case than the screen.

    there are sites out there that aggregate local 3D printing companies and some let you submit a model to get automated quotes from a bunch at once. I found my favourite local printer/supply store that way a few years back. if we have them in Canada then I'd be surprised if there wasn't an equivalent in Australia. there's also services like Shapeways which can print in basic or exotic materials and ship them

  My library has one, and it's saved me the itch of wanting my own printer a few times now. I have made a deal with myself that once I print things regularly enough, I can consider getting a printer of my own, but at the current clip of maybe one print a year, it doesn't make sense. I'd probably print more if I had the printer, but so far I haven't needed anything bad enough to warrant that, and have plenty of other projects in to which I can sink my money. Plus, picking up a print gives me a reason to go to the library, which I love.

Many public libraries have 3D printers you can use, or they will print your files for you. Some even have 3D laser scanning to create duplicates of existing objects.

Before 3D printers were so common, the way you’d solve this problem was to buy an enclosure and modify it (cut out a hole) for the monitor to fit into. There are many options for prebuilt enclosure/cases, so I’m sure you could find one with the right amount of space and size for this project. 3D printing will yield a more custom solution that fits exactly the size you need. But that’s a pretty recent advancement and there are alternatives.

Ask around if any of your friends have a 3D printer. For a one-off personal project that needs an RPi case most people with hobby printers would probably not mind. It costs pennies in materials, the only thing it uses is printer time, and hobby printers are usually idle 90% of the time. For electronics housings, the material should be PETG, ABS, ASA, or any variant of nylon. PLA is a bad choice an RPi case, it will warp under the heat.

At home, 3D printing is a highly skilled craft and takes lots of experience and expensive hardware. I have been doing 3D printing for a decade, and have been through all the pitfalls. It was a long hard road to get consistent quality prints. Sure, if I need something prototyped really rapidly then I'll print it at home. But if I want something done with exceptionally high quality, then for me its much easier to design the part, I use OpenSCAD, and then send the STL to one of the many 3D printing service providers to be printed. My personal favorite is JLC. They offer lots of different materials, and their commercial industrial 3D printing machines do a much better job than any DIY home printer.

  > I have been doing 3D printing for a decade, and have been through all the pitfalls. It was a long hard road to get consistent quality prints. A decade ago, I would have agreed. The situation has changed so much in the past 2 years that it's not very difficult to get high quality prints from a modern printer. Sending files to a professional 3D print shop will produce better parts, but it's nowhere near a necessity for something like a simple Raspberry Pi case. Those projects are perfect for the latest generation home 3D printers.

    I have fdm and resin. Bambu absolutely changed the fdm world. But for resin if I need something done perfect, I just send it off. I’ve had 100% success rate on all the resin prints I didn’t print myself. Anyway.
