Large Combination Lock - Remodel, Scalable

thingiverse

This is a complete overhaul of the large combination lock by @EGauthierEAO. * This version requires no bolts, but rather snaps together seamlessly. * It scales nicely to 50%, unlike the original, offering a more compact design. * The face plate features sunk numerals for improved print quality and clarity. * No support is required during printing, thanks to its clever design. * Friction tabs are used to eliminate free wheeling and ensure smooth operation. A plate with all parts scaled to 50% is available for printing, which I highly recommend as the ideal print size. All the components are aligned for printing without support. To achieve optimal results, I suggest printing at a slower pace when dealing with smaller parts such as the push pin and LockDisc. Please feel free to comment and post your creation! Below is the development log, where I'm considering adding a gear system to enhance accuracy and enable multiple complete rotations: 1.4 The base has been modified to feature separate friction poles for easier printing and greater robustness; the poles have been sliced to facilitate printing on flat surfaces. Friction plates 1.21 and 1.22 have been updated with increased friction levels. A chamfer has been added to the edge of the poles on the base plate for smoother assembly. 1.2 The track of the latch has been shortened by 2mm. Rollers now feature rounded entrances with a 3mm radius. Friction tabs and spacers have been integrated into the top plate, along with adaptations for friction in the base. A full STL plate is available with 50% scaling and correct orientation for print without support. 1.1 Redundant poles from the base and top have been removed to simplify the design. The height of the top roller's main radius has been reduced by 1mm to clear the top plate. The U bolt radius for the latch, as well as the latch hole radius, has been increased. The lock design has been revised, including the slide, which is now a U disc. 1.0 Initial modeling of the lock took place, featuring three direct motion rollers. The face plate features embedded numerals for added visual appeal. The top roller includes a slot connection to the dial. The push2 pin was deemed unnecessary, and the push1 pin installed from the top proved sufficient. https://www.youtube.com/watch?v=6i_D6XqJ01A&feature=youtu.be
