7 Segment Counter v2.0 Tutorial, 3D Printed, STL Files Link

Version 2 of the 7-Segment mechanical counter. Improved design. This particular model is a sequential counter (numbers 0 - 9) that receives a linear input to cycle the display.

Files updated on 5/5/24 to use 3D printed screws; no longer requires wood screws.

A potential feature idea is to have carryover output/input so you could chain them.

That has to be the best project ive seen for a long time - bravo. Tempted to make a clock using steppers with it

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

Finally a handheld way to count to ten

Can be argued as being a bit big and clunky, but this is rather driven by the limitations of the 3D printing and associated materials.
The design, however, is absolutely exquisite in its elegance and I truly love it. Masterful !!!!

Compliant springs in place of the bands and a way to link multiple together would be fantastic upgrades. Great project, thanks for sharing! :)

I printed this for my numbers-obsessed kid, and he loves it - he was very excited to help me put it together! And thanks for adding the printed screws, saved me a trip to the hardware store.

This is a super impressive project considering that the only non-3d printed things needed are rubber bands and a couple screws. You could probably even design it to be held together without screws. Super impressive. Well done.

Given how simplistic the mechanism is, this could very well be shrunken into a very slick mechanical watch. Would LOVE something like this on my wrist.

What a beautiful design! Assembly so satisfying that I am going to print this, assemble it and then take it apart and give the parts as a present.

Your video serves as the assembly guide.

I design, build and fly radio control airplanes as a hobby. As a designer, I appricate how much work you've put in your project. Job well done and 2 thumbs up !!

Wow! I love this, thank you for making the files available for all of us. I immediately thought of using it to make a counter for our sports match, which is currently made out of paper and no one wants to go there and turn the number after a goal. With this tactile feedback, I wouldn't be afraid of it. xD

So I basically need to connect two double counters together!

[berni_schmorg]

I love this design a lot! A lot of these highly complex models are insanely difficult to assemble but this is poka yoke heaven! Product design mastermind.

Mechanical engineering making a comeback of note.

[marcor]

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!

[sceptrdisle]

Thank you for sharing this and making the files available. Very well designed and explained. Great for helping my grandchildren to count!

[tymofiidanylevskyi]

I think the design of this product is very beautiful, this is how products should be made. Pragmatic and reparable

[orange_district]

Pretty impressive! Purely mechanical projects are so satisfying.

i am happy I landed on the good side on Youtube. Subscribed. What you have given me is ...food for thought. I may or may not attempt this...but there are many things I learnt from this video. Thanks a bunch!

[Nifty-Stuff]

WOW! Why did the Youtube Gods take so long to show me your channel!?!? I'm printing this and subscribing. Keep these free designs and great videos coming!!!
