I wanted a clip-in filter for my Lumix and perhaps you need one as well? A fast print to make. Please note, the inner diameter of the M43 adapter may vary. This one has a snug fit for a M43-M42 (screwmount) adapter by Dollice.
Align the dots and insert carefully the adapter to your Lumix. Pay attention that the contacts in the camera body is not damaged. Tighen adapter and the filter adapter should slide and not touch the contacts.
