Octoprint Pi Zero2w/Pi2/3/4 enclosure

Description

I uploaded the wrong file for the pi3 base in my original upload Accidentally selected export all instead of single stl so it is a charlie foxtrot file) . I replaced the bad file with the correct file around 12 hours later, so if you downloaded it early and need the pi 3 base, then you will need to download this corrected fileset). UPDATE Dec 21. Added Pi Zero 2 mount as we can now use the zero 2w with octoprint. Pi 3/4 enclosure with options for tools and gopro camera mount adapter. I needed a more useful case/enclosure than the simple case I was initially using. I designed this to be both simple, but also useful. It has mothernoard (mobo) bases for both pi3 and pi4 (they are different, so choose the right one). The pi3 base is good for pi 1/2/3/3b/3b+ while the pi 4 is 'believe it or not' for the pi4. There are a set of motherboard fasteners in one of the stl files. I did 5, you only need 4. But by their very design they may fail when fitting if the tolerances are too tight on your printer. Although shown as pi 3 fittings, they will also work with the pi 4 base holder. I mainly wanted to hide the wiring for the pi. With this design all the wires except the camera cable are totally hidden and run underneath the printer. Power and usb wiring all comes into/out of the left side of the enclosure so the unit itself looks best on the right of the printer. If you are planning to use it on the left of the printer I would just use the standard enclosure (without tool storage options) and rotate it so the back is facing the front and the wiring still goes under the printer. I am in the middle of a quick design add on that would compliment that look well. It should be done by a day or two after this was written. I have included the stl file for the (TPU) feet I am using with my printer that raised the printer sufficiently to allow the enclosure to sit flush against the printer with the wiring easily slipping under the printer. That flush fitting may not be possible without that small height hike. There is a slice/aperture in the top of the case to allow a pi cam cable to exit cleanly from the enclosure. I primarily designed this to not need screws. However, fitting a fan may need screws or whatever alternative you have for fan fitment. This case was designed to take a 30mm fan if required. A pi3b does not need active cooling. A Pi4 however will. You have multiple options available after printing the enclosure. You can leave it as it is. Or you can add one of the tool holders. One holds three tools with the first blanked short to protect the pi cam wire. The second has those same tool holders, but also sports a GoPro adapter built into the design. The optional octoprint front panel is also supplied here. The main larger enclosure just slots over the top of the pi and its base. There are no securing tabs required. It was always meant to be a simple but effective design. My first version slotted over a standard pi case (the cheap ones you can get for a couple of quid on ebay or amazon). This fully 3d printed version was a logical upgrade and with the addition of the pi4 facility, it added the need for a fan mount option. The opening for the fan has a built in grille to help keep things out of the opening, especially if you do not choose to fit a fan. Although almost identical in size, this design has been tweaked a lot over my original design. The original is likely still on my list, but this should be considered to be the replacement for the previous design. PRINTING:- it should not need supports. Use common sense for printing and it will be fine. The only potential difficult area would be the go pro mount. You may need to clear the holes a little after printing if you decide to not use supports. But I do not see any issues at all in printing without supports for all the files here.
