Quick return mechanism
thingiverse
In this project, I followed the design from the post: https://grabcad.com/library/quick-return-mechanism-1 and created it using Diamond Age PLA on an Ultimaker 1. To enhance its performance, a short video was shared at http://youtu.be/rxKYPUHeap4. After completing the usual finishing touches, I discovered that lubricating the mechanism was essential for smooth operation. Conveniently, I used olive oil, but there are likely better alternatives available.
