Charging dock for Nintendo New 3DS

myminifactory

A fully functional charging dock for the New 3DS comes complete with swappable plates that can be printed in multiple colors. Best of all, this works with most printers because you simply have to change filament at certain heights. I took extra care and designed it so you don't need any special tools or components, just a bit of wire and spring from an old pen. Everything is also printable 100% without any supports. I've made a build video if you're interested: https://youtu.be/3dQFI1BClfM. Looking for the XL version? I'd love to include it as well. If you have one and are willing to take measurements, please get in touch and I'll design the XL dock too. Adjusting the pin contacts When adjusting the contacts on top of the charger, try shaping them into a V shape. It can be tricky and you may have to try it several times before making good contact. Don't give up! Adjusting the spring The stiffness of the spring is very important. If the spring is too strong, it will tip tilt the 3DS and lose contact. If it's not strong enough, it won't push against the charging contacts. You will have to tinker with the spring until you get a good fit. I did it by cutting away one loop at a time, putting the spring back in and trying if it works. Keep doing it until you get a reliable contact. Multi-color printing For printing in multiple colors, you need to slice the model and save it as normal gcode. Then, insert the M600 command. You can do this manually by opening the gcode, but the easiest way is to use the ColorPrint tool by Prusa. Simply upload the file, set height changes and save the new gcode. Here's the tool: https://www.prusaprinters.org/color-print/. If you're interested in how to design things for multi-color printing, you can watch my video that explains everything: https://youtu.be/KsbE2vEzS7U. I'm also including a blank plate so you can design your own. Import it into CAD of your choice (I recommend Tinkercad or Fusion360). The first layer is 2mm thick, every subsequent layer should be 0.8mm. Here's a list of heights and colors for each particular plate: Question block Start with BLACK, then at z2.2 change to YELLOW, at z3.0 change to WHITE. Mario hat Start with RED, then at z2.2 change to WHITE, at z3.0 change to RED. Brick Start with BLACK, then at z2.2 change to BROWN. Bullet Bill Start with WHITE, then at z2.2 change to BLACK, at z3.0 change to WHITE. Yoshi Start with ORANGE, then at z2.2 change to RED, at z3.0 change to WHITE, at z3.8 change to GREEN, at z4.6 change to BLACK. Mushroom Start with BEIGE/SKIN, then at z2.2 change to WHITE, at z3.0 change to BLACK, at z3.8 change to RED, at z4.6 change to WHITE.
