mini drill press hackSince nobody but me has this exact, ancient binocular microscope ($20 flea market bonanza), the STL file is useless. But the idea may be worth something. People might have done a similar scope-hack and if so, credit to them. I had to drill a bunch of very tiny holes in steel using the delicate solid carbide micro-drill bits from Harbor Freight. Although I planned on printing the whole drill press from scratch, the scope's large, stable table, precise rack-pinion vertical control and dovetailed ways was too attractive. Everything was easy, from design to print, and it worked on the first try, so I thought I'd share it. For stability, sections are thick at 0.25 inch. Part weighs 47g plus 10g support. It was a two hour print using "Normal" quality and 0.30mm layers (Afinia default settings). There's a big enough hole in this scope's frame to fit the Dremel tool itself, but I didn't want this frame to suffer the weight and torque, and the design would be more complicated, so I chose the flex shaft (with a foot switch). The flex shaft has a straight 0.5 inch diameter body and fits really tight in the 0.5 inch hole. No nut / bolt is required across the split flanges to secure it. Chips and dust go everywhere so the next thing is a protective cover for the mechanism made from plastic wrap or something. And then maybe attach a large magnifying glass..
