Roll bender

We design and develop experiments for kids in STEM education at Uni. One such experiment visualizes how the hadron collider works and how the solenoid functions. As a result, we have this: To create this experiment, we need a roll bender. Unfortunately, finding a small one that's also affordable is really tough. After some research on Google, we find this tool and later this other one. With designing and development, we come up with our own version of this tool - it's robust and 3D-printable. Materials and Methods: Print-settings: Our model is fully optimized for 3D printing. Support/rafts: None (if you're unsure about your printer, add touching build plate support). Layer height: 0.2 mm Material: PLA plastic Shell line count: 3 for rollers, 5 in total. BOM: 4 bolts M8x55mm (for passive rollers and top mount) 2 bolts M8x35mm (for handle) 1 bolt M8x85mm (for active roller axis) 1 anchor bolt (for the slider - this bolt must be filed as shown on images and glued in knob and ball inside the slider) 1 bolt M8x100mm with rectangular slot (for lever handle) 4 608 ball bearings 8 nuts M8 1 piece of 10mm x 80mm aluminum tube (for lever handle) A tap for threads Some mood for needlework
