Sonos Era 300 Flexson Stand Adapter

I had Sonos One SL speakers for my home theater surround speakers. I've upgraded them to the new Sonos Era 300 speakers and did not want to have to throw out my perfectly good speaker stands. This adapter replaces the top portion of these stands to allow a Sonos Era 300 speaker to be solidly bolted to the Flexson stand.

You will need:

• Sonos Era 300 speaker
• Flexson Floor Stand for Sonos One or Play:1
• Two M5x20 countersunk screws for each speaker
• Two M6x30 countersunk screws for each stand

The two countersunk screws that come with the Flexon Floor Stand are too long for this use and shorter replacements will need to be sourced (or simply cut about an inch off the original ones).

Worth noting is that the power plug on the Era 300 is larger than that of the Sonos One - so you will not be able to route your cable through the small hole at the base of the stand.

I basically just butchered the fine work done by @agentdr8 to fit my mount.
