Empty Spools Make Useful Tools, Like Counters

Empty Spools Make Useful Tools, Like Counters

What is the deal with receiving items completed? You can find a Seinfeld anecdote that boils down to this: get a calendar, do a factor, and make a significant X on each day that you do the detail. Pretty before long, you will thirst for chains of Xs, then you may want to black out the thirty day period. It really is good guidance.

[3D Printy] likes streaks as well, and built many resolutions at the starting of 2022. As the to start with of 30 movies to be manufactured through the calendar year, they featured this huge 3D printed counting mechanism (movie, embedded under) that takes advantage of vacant filament spools, some 3D prints, and not significantly else. These are all Hatchbox spools, and it would not operate for each and every sort, but the style must scale up and down to suit other flavors.

This is not [3D Printy]’s initially counter rodeo — he’s made a number of more ordinary-sized kinds and perfected a clever carryover system in the course of action, which is of program open up-source. So just about every spool signifies a single digit, and there are printed areas in the main that make the rely carry more than to the future spool. Whilst the early counters utilised threaded rod, this giant variation rides on 2.5 mm easy rod, so the spools can slide apart effortlessly. But how does every little thing stay with each other? A large elastic band manufactured of TPU filament, of study course — mainly because the answer is often in the area.

Check out out the online video after the break, and continue to be for the 900%-sped-up assembly at the finish.


Thanks for the tip, [Zane]!
