Raspberry Pi Baseplate

thingiverse

The Raspberry Pi 5 has numerous minuscule SMD components soldered to the rear of its PCB. This baseplate will protect them while you are driving your Pi 5 as a cabriolet. The baseplate fits the older Pi "B" models as well.The four screws have the dimensions M2.5 x 8 mm. The (nominal) 2.4 mm holes in the baseplate should be just right for the screws to cut their threads themselves. Do not slip off with the screwdriver as there are delicate components nearby. Do not overtighten.====================================================================Update 26 January 2024:Added rounding of the lower edges to prevent elephant footAdded optional screw cups to prevent screwdriver slip, therfore protecting nearby components: First insert the screws fully into the cups (the screws will cut a short thread into the cups' bottom hole), then screw the screw+cup combo through the PCB holes into the baseplate holes. The cups have very thin walls (0.5 mm); you may have to configure thin wall options in your slicer (e.g. Process/Advanced/Thin Wall Behavior/Peripherals/Allow Single Extrusions in Simplify3D).====================================================================If you have only longer screws than 8 mm you may proceed as detailed below, adapting the l_thread parameter accordingly.As always I include the OpenSCAD source file for you to adapt and/or improve:Download and install OpenSCAD from https://www.openscad.orgLaunch OpenSCAD and open the enclosed OpenSCAD source file (/File/Open).Amend the parameters at the top of the file or even amend the code.Save your changes (/File/Save).Render the design (/Design/Render).Export the rendered design e.g. as a .stl file (/File/Export/Export as STL).Slice and print.See my other designs athttps://www.thingiverse.com/thinger13/designsIn particular:https://www.thingiverse.com/thing:6500953https://www.thingiverse.com/thing:5204103
