18650 hand drill

thingiverse

I frequently use my dremel for small tasks, which can be frustrating when it takes me a full 30 seconds to retrieve it from my toolbox. Recently, I repurposed a DC engine from an old RC boat and some spare 18650 cells from an outdated laptop battery to create a compact hand drill. The links provided are simply examples; I purchased my components some time ago. Here is the list of parts needed for this project: 1. A 280-type DC motor (https://goo.gl/i3ZrLd) 2. Two 18650 batteries 3. A mini drill chuck (https://goo.gl/J5sN43) 4. An endstop switch measuring 20x10x6mm 5. A M3x16mm screw 6. A M3x25mm screw 7. A M3 nut 8. A rubber band 9. Some spare cable with a 2.2mm thick insulation Additionally, you will require some Dremel accessories if you do not already possess them. In the revised version of this project, I concealed the cables within slots. To achieve this, strip about 1cm from the end of each cable and push it into the corresponding holes. The rubber band serves as a makeshift spring to secure the cap in place on top of the batteries.
