OpenFlexure Microscope: USB camera push-fit mount *
*
This is part of the OpenFlexure microscope, an open-source *
microscope and 3-axis translation stage. It gets really good *
precision over a ~10mm range, by using plastic flexure *
mechanisms. *
*
This file defines one useful function, usbcam_push_fit(). It's *
designed to be subtracted from a solid block, with the bottom *
of the block at z=0. It grips the plastic camera housing with *
a "trylinder" gripper, holding it in securely. It might be *
that you need a cover or something to secure the camera fully. *
