Modular Snap Together Raspberry Pi 2B/3B/3B+/4 Case w/ OLED & Fan Options

Description

** This is an ADVANCED print. If you are new to 3D printing please read the entire summary before attempting to print. A few minutes of reading will save you hours of headaches. Compatibility: This case design is compatible with Raspberry Pi's 2B/3B/3B+/4. It may be compatible with other models, however, these were the ones I was personally able to test it on. No Hardware: This design does not use any hardware and all parts are “Snap-Fit.” There are small tabs that flex a tiny bit to allow a lip to snap into a groove. Mounting: There are 3 variations of the cases: No Mounting Options, VESA 75 Mount, and a Side Rail Case. The Side Rail case is designed so that users can easily make their own mounting option for the case. Included in the files is “__ss_rail_1_02.STEP” which can be used to design your own mount for the Side Rail Design. Modules: Included in the files is “module_1_01_blank.STEP” which can be used to make your own custom modules. Tips: -This is a “Snap-Fit” design and it uses small FRAGILE tabs to lock together; be gentle. -If you need to open the case back up after snapping together, remove the SD card, stick a mid-sized flat head screwdriver between top/bottom at SD slot, and twist gently. Slowly work your way around to open back up. -If you need to remove a module, there is a release slot on the back of the case (Small rectangle). Stick a small flat head screwdriver in and gently pry up. This will raise the module high enough to access the recessed slot you can get a thumbnail or screwdriver in to pull off the module. -Did I mention BE GENTLE? Seriously, I've broken a lot of these by pulling too hard or being impatient. A few seconds of patience will save you 4 hours waiting for another printed part. File Structure: I have separated the different versions into STL sets. The file names reference the model and mounting style. The modules are available in both a set and individually. Fan Module: The fan module uses a 40x40x10mm fan. I have tried tons of manufacturers fans and they all snap in the module perfectly. The trick is to gently insert the fan straight on (not crooked). Getting it back out is a bit trickier, in fact, I typically break the tabs trying to get the fan back out. This is the limitation of making a Snap-In module with a 3D printer that uses layers. OLED: I have a document on how I got the OLED wired and what software was installed. The file is a very rough outline; if anyone wants it it is <a href="https://docs.google.com/document/d/16J9nb1cVOs4RNV5Xy3nwUGniZ36lozZXrX8V6RZvFtM/edit?usp=sharing">available here</a>. It is a work in progress and I will keep updating. Rails: I have uploaded rails for several mounting options including a Prusa MK3S rail, Mini Rail, and a Left/Right Wall Mount rail. The Prusa MK3S rail uses the two open M3 screw holes directly above the control box. There are also two rails for the Prusa Mini. One Rail is designed to mount your Raspi on the 3030 behind the controller, and one is designed to mount your Raspi on the 3030 in the Rear Left corner. Both of these rails can be used to mount your Raspi in many other places too! I have also included M3 Roll Nuts in the design The Mount behind the Mini Controller Requires 2x M3x12mm flathead screws and 2x M3 nuts. The Mini Rear Left Mount Requires 2x M3x18mm flathead screws and 2x M3 nuts. Files: I did my best to organize files. The name of file indicates exatly what the part is. if you have a Raspberry Pi 4, look for all files with" rp4." 2/3B/3B+ look for "rp3bp" in file name. "v75" is for VESA Mount, "ss" is for side rail mount, neither is no mounting options. ** Disclaimer: This design requires a perfect printer setup. The amount of material on the tabs is so small, that the slightest layer adhesion issue and the tab will break. I have printed and tested hundreds of these on my Prusa MK3S/Mini Printer's and the design is solid. If you are having issues with the tabs breaking, please look at your print settings.
