NES Project

After many requests, I have finally put together a guide to make your own rotary module for your K40 laser engraver! This is a surprisingly simple build and will undoubtedly be the best accessory you will have for your K40! While there are 3D printed parts in this project, I have listed alternatives for those pieces so access to a printer is not entirely necessary.

If you are looking to get a Glowforge Laser, you can use my referral code to get: $600 off a pro, $300 off a plus, or $150 off a basic! I’ll get credit too!

For a Laser that has an even BIGGER cutting capacity and MORE cutting power than the K40 or Glowforge AND still cheaper than the Glowforge. (Sometimes these can come with Rotarys as well, just be sure to double check)
