Production of the microscope
Due to the usage of PETG HF to print our microscope, the tolerances were messed up for the lens tube, in which the small threads shrank making the lens fit very loosely. Additionally, PETG HF was too flexible causing the lens’ threads to slip. The calculation to get the perfect diameter for the timing pulley to create a sustainable pulley and belt system failed, causing to print it multiple times to get it perfectly.
