Hello
where can I get spare parts like camera and others for the OpenFlexure Microscope v7?
@hanggarf there is ongoing discussion of where to find the non-printed parts on the thread Sourcing non-printed parts. You may find some help there, or post there what parts you are having difficulty finding. Where you are can also make a difference to the supply.
For the camera, the Raspberry Pi camera V2.1 is generally available from electronics suppliers and maker suppliers, except that in some regions many places only stock the newer Camera Module 3. The Camera V2.1 is still a current model, so you should be able to find it somewhere.
