Yoto Gen 2 USB-C Charger Adapter

I got my Yoto second hand without a charger, and not feeling like drilling holes and adding a USB-C port directly to the Yoto (e.g. iFixIt ) I designed this as a replacement. 

The base is magnetic and snaps into place on the bottom of my Yoto and charges fine in that position. Unfortunately the magent I had on hand is a bit weak, if I was to redesign this or update this, I would probably go with a larger and stronger magnet.

Notes

• The positive ring is the large one, so solder the red wire to the outside ring and the black wire to the inside ring.
• The data wires are not used, the USB-C connector was just cheaper with 4 leads instead of just the two, just cut them off so they don'thave any chance of  shorting out.
• Test fit all the pieces after removing the supports, it's likey you may need to scrape some plastic away to make it sit flush.
• The crush washers are very soft and mine didn't even come flat, but a rubber mallet did a wonderful job of flattening them out as well as helping it conform to the groves in the 3d print.
• You will need a hot iron (I had to set mine to 400-450C) since the copper washers act as a great heatsink.
• Lightly sand the copper washers where you plan to solder to help remove any oxide layer.
• You can lightly dust the grooves for the copper in the 3d print to help accelerate the curing of CA glue and to provide additional filler between the 3d print and the copper washers/magnet. 
• The adhesive EVA foam sheet is for the base to stop it from slipping around, just stick it on and cut it to shape with a pair of sharp scissors or a hobby knife.
