The Mini Macintosh WeMos MP3 player is a music player with workable SD card slot on the front. The player can be programmed to operate on autoplay or other components/buttons can be added to control the MP3 player. The player makes use of other components that can found at GadgetsThatGo.com. With the WeMos D1 mini, dual base, and the Catalex MP3 board you can create your own Mini Macintosh JukeBox.

I printed the front face with supports, but the case and holder pin should be printed without supports.
The unit comes together in three parts. The first two parts, the front panel and the holder pin are attached via the two round extrusions on the backside of the front panel. With use of a 1-3/8" #4-40 screw and nut connecting both together.
The dual base also uses four 1/2" #4-40 screws and nuts to secure itself the back panel. When everything is screwed together you can connect all the components with four male to female jumper wires.
After making the wired connections you can slide the front panel over the back panel so that the extrusions on the back of the front panel are tightly fit against the inside of the back case to hold it in place.
