The only flaw in this design is having to glue the segments. I just built mine, and I practically need to punch the button to make it move, while yours moves absolutely effortlessly. I can only assume it's because I didn't glue some of my segments perfectly parallel, so they're binding.

Can you use glue instead of screws?

So if any of the rubber bands should snap then the whole thing brakes

I like how the 6’s have the tops

This is absolutely beautiful - design/theory and execution. Awesome. A mod to allow for servo control (to make a clock) would be great.

This is so next level for me!

Would it be possible to make the gears in a way that it will also substract numbers ? Like instead of shark fins, being symetrical. Thanks!

Thank you so much, for sharing such a wonderful make.

This is SO great. Beautiful design. How about adding another timing gear that can protrude sideways and power a carry in the neighbouring unit. So we can have 2 or 3 chained for larger numbers. Just brilliant bravo!

And now a knob to go back!

This is absolutely brilliant. The design must have taken ages!

You are an amazing person for giving this model out for free. I wish you 20 million subscribers and all the wealth in the world. Have a nice day!

Great design, but I had issues :( Printed in PLA on Bambu X1C, all edges deburred, sanded slots for smooth movement. Checked cam positioning/reassembled 4 or 5 times and the cams just aren't pushing the segs out properly (either not enough 1, 3,4) and 7 doesn't work at all. Not sure what's going on.

Very good job! But smth wrong with PDF-file in 1-digit archive, can't open it. Check it, pls.

Bravooo!

Really cool!! Is it possible to add a button to reduce the number?

hi could you share the stl please you could be earning money i find it useful.hope you consider it.

I'm thinking I could use these in my escape room as a puzzle, would need to add some kind of electronic sensor to make it activate something when the correct numbers are set. I'll think more on that and see what I can come up with

Dude

I like it, thankyou so much, Let me try to printing it

To hide the bars better just paint the side of the bars the same color as the case. LOL

Love it

Bro thats sirriusly good. İ think you set it paid but youre thinking present to community.

The most wonderful thing i've seen... Thank u

i can make a clock with just hour and minute and use a simple timer module with servo to push those slider

thanks for making this free and not trying to nickle and dime people who are just trying to have fun building stuff for free not havibng to worry and have anxiety. i really do apreciate youf or not being irrationally greedy

One thing that's cool about this is that it could be built in any time period in history, if the correct shapes were known, and yet it feels so electronic and digitally driven. Most of our technology requires usage of a long list of previously created tech

wait dude can you make this into a kinda clock??? bc if you could do that i think it would be super fucking cool

millenials invented mechanical calculation

Thank you a lot. This is going to be my 1st project of 3D print as this is so greatly designed and step-by-step guide.😊

I have absolutely no idea what I’d use this for but I want one.

Hey! Flower 3d a year ago I successfully re-created an earlier version of your clock it looks about the same without an auto rewinder. (I’ll use snap circuits to make a switch) and currently does not have a chime (need bell) However, it is functional. I am planning on adding a day clock to the side and 3-D printing some gears! I would like to ask you though when will that new clock video come out? I was hoping to see it in its current state. That is all I have to say for now. Thanks, ATLAS (the K’NEX person)

This does not work for me.

This is awesome! is there anyway to make it count down though?

Hey! If you see this, would you ever consider selling these please? I don’t have a 3D printer but would love one for crochet stitch counting!! Thanks :)

amazing

Im printing 2 of the 2 segment versions for a competition im holding. THANK YOU!

Very nice, a slight improvement would be to add 4 small posts for the first band to hook over, a rectangular format slightly inside the returned position. This would reduce the force on the top and bottom pieces as it would be more of a deflection than a stretch. But it's a wonderful model

Beautiful project, congratulations, I'd love to have a 3D Printer to try it, really good stuff, it is wonderful what it is possible to do nowadays with one of those machines, thanks for sharing!

Wow this is very impressive. How did you go about designing the CAMs? trying to imagine it mentally and its hurting my brain! Maybe a design video would be interesting! Very cool design and great video!

Incredible genius design. What do you have in store for v3? full x86 emulation?

you should charge for the designs. i was ready to pay. too good! thank you for building.

Maybe 3d print the screws too

At first this looked pretty cool. Decided to build the dual one as a present to someone who teaches children with special needs - thought it could be used as a teaching a. After a week of tinkering I have come to an understanding that the biggest flaw of this design is the thickness of the followers and cams and too tight clearances between different cams. After several days and evenings of sanding and filing the parts the followers keep getting stuck or not actuating (slipping past the correct cam). If the cams and followers were thicker with bigger gaps between them, the assembly could have been more repeatable for everyone using different printers. I'm using Prusa Mk3s+ and found out that turning on the ironing for the cams and followers helped to make them really flat and with acceptable tolerantces. But still... I can't give this unusable counter away as a present unless I wan't spend the next year finetuning it.

by gods i need a magic the gathering megacounter like this

What The Brain!!!

Interesting project, my first thoughts were a clock or multi digit counter, then I saw you did a clock video using it. Subbed, curious to see what else you come up with.

Incredibly ingenious

I am not sure why anyone would want something like this, but it is very interesting.

Fantastic work here!
