Nintendo New 3DS Charging Cradle (Normal and XL)

thingiverse

This is a charger dock/cradle for the Nintendo New 3DS, with versions for both sizes. This project started to solve some problems I had with [this dock from Hackaday](https://hackaday.io/project/163630-charging-dock-for-3ds-with-swappable-plates), and I ended up totally redesigning it. Here's a list of this dock's major features: * It makes contact using pogo pins, which are simple to install and reliable. * The wiring is covered by a door secured by a standard M3 machine screw and hex nut, making it easy to assemble/disassemble. * High walls keep the 3DS secured in place, but it still fits loosely enough to easily slide in and out. * Splits in the walls over the sliders and an indent around the cable port make it easy to hide seams. * The notification light is visible through a small window. To make this dock, you will need: * 2x 1mm diameter pogo pins ([I used these](https://www.ebay.com/itm/100pcs-1-5mm-Pin-Head-Spring-Loaded-Signal-Test-Probes-Pogo-Pins-Connector/153105851762?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649)) * 1x 8mm M3 machine screw * 1x M3 hex nut * 1x USB cable * A soldering iron (and solder) * Glue of some sort I'm really happy with how this turned out, I hope you like it too! These are the files you'll need for each version: - Normal New 3DS: N3DS_Dock_Cradle.stl, N3DS_Dock_Door.stl - New 3DS XL: N3DSXL_Dock_Cradle.stl, N3DS_Dock_Door.stl - SNES New 3DS XL: 3DSXL_Dock_Cradle_SNES.stl, snes_mmu_logo.stl, snes_mmu_text.stl EDIT 3/14/2021 (Pi Day!): Finally uploaded new STLs in the correct orientation, and threw a decent thumbnail in too. That 500kb limit really got my salt flowing... EDIT 11/7/2021: Got my hands on an N3DSXL, figured I'd make an XL version of the dock. Part of this process involved recreating it in CADQuery, the script for which I've provided. It's a little different from the Inventor version, mostly just with respect to the fillets at the bottom of the volume/3d slider slots, but it should be exactly the same in terms of fitment and functionality. Let me know if there are any problems. O3DS version coming sooner or later. EDIT 11/21/2021: Finalized the 3DSXL design (slightly wider with larger radius fillets inside the slot), changed all meshes to the new CADQuery version, added an MMU SNES-themed model! EDIT 11/22/2021: Updated the CADQuery script to let you move the pins along both X and Y, export STLs and STEPs automatically, plus a few readability improvements.
