Sonos Roam Wireless Charger Base

A base for holding the wireless charger for Sonos Roam. I have designed this fix the annoying problem with the wireless charger sticking to the Sonos Roam when picking it up.

The charger is too light and doesn't stay on the table when picking up the speaker, also it has some silicone coating making it impossible to fix it with just some double sided adhesive. I have designed this base to fix that problem.

The slot for the cable is intentionally slightly off center, this is to provide some tension with the cable to make it stay in the base.

The shape of the charger base is super difficult to measure, I've made this as accurate as possible by printing loads of test peices until I got a good fit. Therefore no guarantees that it will work on your printer.

The shape being odd is also very difficult for Fusion to handle, therefore there is a small artifact thin plane that shows up both in the slicer and is slightly visible in the final print. I think it comes from some rounding error on some floating point number, as the shape consists of multiple curves. It's not a big issue, so I've concluded it's best to live with it.

I've printed this on a Prusa Mini with 0.6mm nozzle, 0.1mm layer height. To add weight I've used 10 bottom layers and 5 perimiters with 30% infill, with this it stays on the table when removing the speaker by tilting it slightly, but sticks if lifting straight up. It's possible to add some double sided adhesive tape to fully stick it to the table, if needed.

Note: This print only fits the wireless charger as the charger is slightly smaller than the speaker itself. The shape is the same, but the speaker will not fit into the base without the charger.
