GPS Spacer Ring for TomTom

One of the problems with the TomTom magnetic glass mount is that over time the suction pad becomes loose, ineffective and the TomTom falls down repetitively. I have designed a simple spacer that can be placed over the existing suction pad to improve suction and extend the life of the magnetic glass mount. My GPS was a TomTom Go 520.
Printed in black PLA+ with 40% infill. No support needed.
Still early days, but appears to work well.
