Microscopy Mount sample retianer ring

Used to fix sample to microscope slide with resin and then circular cover slip placed on top and cured.
- The PLA hold up nicely in the curing oven @ 50*C and does not warp.
Two sizes rings, (9mm ID & 11mm ID) both 2mm tall with 1mm wall thickness, for the two sizes of cover slips used due to specimen sample size variations.
The round cover slip will fit perfectly and rest on the wall of the ring providing a flat horizontal surface for good microscopy results.
