I've recently been showed this video on social media and been inspired to create a 3D printable version of the binary counter. It's been a great design challenge for me and I learned in the process.

This makes for a great educational tool and ab equally great printing project.

Features :

• No support prints
• 2, 4, 6 & 8 bit versions available
• All versions fit one one A1 Mini buildplate
• Smooth action and sleek look

Printing :

If you are not using the provided print profiles, make sure you print the following files

• n-1 x Numbers file (n=2, 4, 6 or 8 bit)
• 1 x Final Number
• n-1 x Pins
• n-1 x pivots
• 1 x Left Support
• 1 x Right Support
• 1 x Support Beam (get the corresponding bit version)
• 1 x Rod (get the corresponding bit version)

Assembly :

1. Slide and glue in the rod into the right support
2. Take the pins & pivots and attach them to the numbers, it's a tight fit
3. Slide in the numbers assembly onto the rod
4. Slid in the final number onto the rod
5. Slide and glue in the left support
6. Glue in the support beam at the bottom
