Roll bender

thingiverse

We're actively involved in developing and teaching experiments for STEM education at Uni for Kids. One such experiment we've been working on is visualizing how the hadron collider works and how the solenoid operates. As a result, we've managed to create this:  However, developing this experiment required a roll bender. Unfortunately, finding a small and affordable one proved to be quite challenging. After conducting some research online, we came across the rod roller offered by WC Welding and later discovered another option on Thingiverse. Following extensive designing and development, we've successfully created our own version of the tool, which is robust and can be 3D-printed. #### BOM * Four bolts, M8x55mm (for passive rollers and top mount) * Two bolts, M8x35mm (for handle) * One bolt, M8x85 (for active roller axis) * One anchor bolt (for the slider; this bolt must be filed as shown in images and glued into knob and ball inside the slider) * One bolt, M8x100mm with rectangular slot (for lever handle) * Four 608 ball bearings * Eight nuts, M8 * One piece of aluminum tube, 10mm x 80mm (for lever handle) * A tap for threads * Material for needlework
