iFundus Lens Ring Modification

I´ve switched the position of the screws at the lens ring and added some M3 screwheads so you´ll not need any tool to put the lens on and off. As they are in contraposition the screwheads do not touch each other. If you are using any lens larger than 20D (I am using a Volk2.2) you just have to use larger M3 screws and adjust with the screwheads.

Enjoy it !
