Z-height management is the achilles heel of all FDM printers… Anyway today’s print was the OphthalmicDocs fundus scope which allows you to use a 20D indirect ophthalmoscope lens to image the retina with your smartphone camera… Printed great in Prusa PLA. All in one print. Luckily being a 3D printing guy have a large selection of metric nuts and bolts on hand to put it together…
