Polar RS300X Adapter Plate - Updated

As many other users the wristband of my Polar RS300X broke. Therefore I designed this adapter plate so I can mount any 20mm wide wristband to to watch.

After cleanly cutting off the rest of the original wristband you can directly mount this adapter to the button of the watch using the original screws.

As always I added the blend file so you can edit it to your liking.

Update 2023.01.15:

I added a new version of the model having a sleeker design while using less material and be more suitable for smaller wrists.

The new model has to be printed twice.
