M3D Micro Raspberry Pi Mount

thingiverse

This is a secure, unobtrusive, and attractive way to non-destructively attach a Raspberry Pi board to the frame of an M3D Micro printer. The goal was to make it as sturdy and simple as possible while keeping the board clear of the filament and the extruder head. Some hardware is required for the installation of this mount. Print Settings Printer: M3D Micro Rafts: Doesn't Matter Supports: Yes Resolution: 0.15 mm Infill: 100% Notes: Printed with PLA on an M3D Micro with 4 outer walls. The parts are thin, so your infill setting shouldn't matter much. You'll need to print the following parts: (2×) Arm: 0.15 mm layers, self-supports (4×) Spacer: 0.35 mm layers, no supports (1×) Beam: 0.35 mm layers, no supports Post-Printing Remove the support material from the holes in the arms. You may need to clean up the holes a little bit with a razor blade. The following hardware is needed for assembly: (6×) M3 × 10 mm socket-cap screw (6×) M3 hex nut (1×) 2.5 mm allen wrench Order of operations for installation: Place the nuts into the arms. Clip the arms onto the frame. Place the nuts into the beam. Attach the beam using two screws (tightened hard). Place screws through: the board, then a spacer, then an arm, then into a nut. Install all four board screws this way (tightened normally). When inserting the nuts into their hex-shaped holes in the arms, they may either be slightly loose or slightly tight. If the fit is loose, hold them in place while threading the screws into them. If the fit is tight, apply some pressure to force them into place. The handle of a screwdriver works well for this. If the nuts are loose, use a tiny drop of super glue to hold them in place. This is especially useful when it comes to the two nuts that sit sandwiched in-between the arms and the printer's frame. Without a drop of glue, it can be difficult (though still possible) to clip the arms into place without these nuts falling out. Press down lightly on the top surface of each arm's mounting clip while tightening the screws. The goal is to have them sitting vertically (not at an angle) and flush with the top surface of the frame. You can tighten the screws reasonably hard since the mount is held in place via clamping force. Your particular M3 screws may or may not fit through the holes in the Raspberry Pi. If they don't fit through, use appropriately sized drill bits (by hand) to widen the holes slightly until the M3 screws fit through the holes. This mount is designed to be used with M3 (instead of M2.5) hardware because M2.5 (or smaller) hardware can be very hard to find at hardware stores. The shape of the M3D frame attachment clips is heavily based on ilikesanta's M3D spool holder design. The original SketchUp file is available for download.
