UPDATED - Added Pi Zero 2w mount as we can now use the zero 2w with octoprint.

Pi 3 and 4 enclosure with options for tools and go-pro 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 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 extrusion with the wiring more easily slipping under the printer. There is a slice/aperture in the top of the case to allow a pi camera 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 are using for fan fitment. This case was designed to allow for a 30mm fan if required. A pi3b does not need active cooling. A Pi4 likely 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 design 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 large 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 prompted 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. Although almost identical in size, this design has been tweaked a lot over my original version. The original is likely still on the list, but this new version 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 after printing. You may need to clean 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.
