This is a work in progress. I intended to work on the design more but have not been able to due to personal/family matters. Uploading per request and with the hope that someone else may be able to fix the design flaws. Currently it works well with two major issues. 1. the unit breaks at the right mount point after extended use. I've had this happen on half a dozen so far and due to time restraints for the projects I was working on I just kept a spare handy with the intent to try resolving when I had the ability. 2. The activation arm design causes me to loose a section of my printable space. If you get to close to that side of the printer it will put pressure on the filament and stop it from feeding (ask me how I know lol)
For the spring I just used one out of a pen I had lying around. Don't know the brand right now. Also one M3 screw and nut.
For the blade I used a #19 exacto blade although a #4 may be a better choice to resolve the issue of loosing so much print space.
At this time I'm just uploading this as two Step files. 1 for the full assembly and the other for the activation arm. Once the item is more perfected I will reupload individual stl files.
For video of it in action and some more discussion check out this reddit post.
Good luck! And if you make improvements please make sure to share them back :)
