Mini Drill Press Hack Since 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 May Have Done A Similar Scope-Hack And If So, Credit To Them. I Had To Drill A Bunch Of Very Tiny Holes In Steel With 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 To Fit The Dremel Tool Itself, But I Didn'T Want To Suffer The Weight And Torque, And The Design Would Be Complicated, So I Chose The Flex Shaft (With Foot Switch). It Has A 0.5 Inch Diameter Body And Fits Really Tight In The 0.5 Inch Hole. No Nut/Screw Is Required Across The Split Flanges. 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 Magnifier..
