Arduino Mini Pro Holder and Wire Manager

thingiverse

This Arduino Mini holder features a three-piece design with multiple upper assembly variations, including options for a single LED holder, triple LED holder, or circuit board holder. The middle piece includes a 3/8" light Velcro strip to secure the Mini in place while allowing easy removal when needed. Assembly is intended for attachment inside an electronics box or surface-mounted on acrylic, with cable routing notches for wire organization. To assemble, extrude the middle piece, upper, and lower parts in order (refer to image). Clean up with a Dremel, drill bit, or razor blade as needed, removing plastic strings and cleaning out screw holes if necessary. Attach the Velcro strip to the Mini and middle component, then insert the three nuts for the M3x16mm bolts on the underside of the middle part. Screw in the upper M3 bolts to hold the Mini in place, ensuring it's not too tight. With the upper and middle assembly complete, solder wires using the plastic structure as a holder. Organize and route wires in the cable channels, then flip over the assembly and attach the lower part with two small screws. Adjust mounting holes for surface or project box attachment if desired. The design includes options for a tube for the reset button and a mount for a 5mm LED, which can be removed if not needed. Future versions may incorporate a battery box and space for a commercial electronics board.
