Prusa Case for Raspberry Pi 4

thingiverse

This design is for the Prusa Bear full upgrade and was created to match either the original Einsy Rambo case or one of the SKR cases I designed: v1.3 - https://www.thingiverse.com/thing:3929513 v1.4 - https://www.thingiverse.com/thing:4723441 This case was specifically designed for use with the Raspberry Pi 4 board and if you want to use it with any other versions make sure that version will fit. It provides full access to all the labeled connectors. There is the addition of an access labeled “SC”, this was added to be used with any Security connections a user may want. I am creating a smoke detector shutdown circuit for my printers that will disconnect AC power to the printer if the detector is activated. I am doing this since the cause of printer fires is electrical – no power, no over-heating or sparking – hopefully fire avoided. The code will even send a text to me if the detector is activated. That is why the SC hole was added. There is even an access for the camera flat cable. Use 2 – 3mm screws to mount the two case mounts to the case itself and 5mm screws with nuts to mount to the frame. The RPi can be mounted by using one of two methods, either 4 – 2,5mm screws directly to the case or 4 – 2mm screws and mating nuts. For this I used the 2,5mm option and it works great. The cover has two variations so pick the one that will work best for you. • RPI4-cover_12mm – can be used with the hinges, but will not close correctly if mounted like I have mine – see the pictures! • RPI4-cover_18mm – this is the cover shown in the pictures. Test your fan mounting to ensure the fan is pulling air from the case and not blowing into the case. This will keep the bed from getting any unwanted cooling effect. Hope everyone finds this useful. Both stl’s and scad files are included for the parts I created. The mounts and hinges were modified stl’s from the Bear Upgrade and saved as such.
