작가 설명
READ BEFORE PRINTING! This is a non-commercial print, this means you are not allowed to sell files or prints of this model. ___________________________________________________________________________________________ This is my fifth attempt on creating a mechanical tally counter. It's adjusted so anyone with a reasonably dialed in 3D-printer will be able to print it. There are some non-printable parts but they should be easy to find at home, in any hardware store or as in my case, the grocery store. I said earlier that I wouldn't continue developing this project... I was wrong. I found far too many ways to improve on the v.4 design to ignore it. Version 5 is based on the v.4 mechanism, but a lot more compact and easier to assemble, as seen in the pictures.The key added in this project is also works for version 4! ___________________________________________________________________________________________ Videos and assembly instructions: A PDF assembly-instruction can be found among the download files. The key works both as a tool to screw together/apart the case, as well as a crank to reset the dial to any number. Assembly instructions and demo (Animation): How to use the counter: ___________________________________________________________________________________________ Troubleshooting: Heres a list of problems and some possible solutions. If your problem isn't in the list please let me know what the problem is so I (depending on the problem) can add it. ------------------------------------------------------- Problem: My buttons stick when I press them down. Solution 1: Clean your prints from any brims etc. No movable parts should have any significant friction. Solution 2: The pen springs you used might be too weak. Solution 3: Loosen the screw on the back of the back case, you might have over tightened it. ------------------------------------------------------- Problem: My buttons are loose. Solution 1: The pen springs you used are too short, they should be over 23 mm long in order to be slightly pre-tensioned. ------------------------------------------------------- Problem: The Dials move but doesnt align with the window on the front case. Solution 1: Make sure you followed the dial assembly step correctly. Solution 2: Clean your prints from any brims etc loosen the screw, and make sure all parts are pushed together correctly. Solution 3: The pin spring is too weak, try swapping it with another spring or a longer spring piece. ------------------------------------------------------- Problem: The first digit dial turns when I press down the button, but turns back again when I release the button. Solution: The rubber band is way too strong. The ratchet arms doesn't fold on their way back, which means the pin slips. Change to a rubber band which is barely in tension when assembled. ------------------------------------------------------- Problem: The mechanism is sticky specifically when the second digit dial is

PRINT SETTINGS - Print all components in the default orientation to minimize support and maximize part strength. - Don't use raft, Rafts tend to give the bottom surface a rough surface fininsh. It can mess up the tolerances, which will/can make the mechanism "sticky".If I have problems with bed adhesion, I always use a brim! Just make sure the brim is entirely removed. - Support materals are only required on "second-digit-dial", I wouldn't recommend using support materials on any other part, especially not the Back Case. It shouldn't be neccecary as all other parts are designed with either "bridges" or a 45 degree overhang. - "first-digit-dial" and "second-digit-dial" are designed to be layered with two different filament colors, it isn't required but it makes the digits "pop" a lot more. The same goes for "Left-Button", "Right-Button" and "Front-Cover". See the pictures and videos for inspiration. - Make sure to break loose the screw on the "back-cover" before assembly. This part can partially fuse with the rest of the back-cover. - Clean all printed parts from brims, support material, uneven surfaces etc! The tolerances in this project are quite lenient, but major flaws might still make the mechanism "sticky". ___________________________________________________________________________________________ PART LIST (BOM) PRINTED PARTS:1x left-button1x right-button1x left-button-arm1x right-button-arm1x front-cover1x back-cover1x ratchet-wheel1x ratchet-wheel-cap1x pin1x 4-tooth-partial-gear1x gear-lock-ring1x first-digit-gear1x second-digit-dial1x first-digit-dial1x key NON-PRINTED PARTS: 3x The tip spring of a pen (one for each button and one for the pin).1x Small rubber band(approx. 120-140mm long), this rubber band should be small enough to be in tension when hooked on the button arms. However, a too short rubber band might not allow the arms to fold properly. It should be possible to cut a longer rubber band and tie the ends together to adjust the length
