Timelapse Trigger Mounted on Prusa Mk3s X-axis Left Motor Side

thingiverse

This was an attempt to mount the trigger for a DLSR in order to do timelapses. My RPi 2 was struggling to have Octoprint doing prints in a timely manner and the web cam was making it worse. So I though I'd take the manual route and designed this. The original idea was to actually house the camera trigger in a slot. Thus the mount was made and a slot made to attach and refine the trigger. I used a prior design as a blueprint for the motor side, though it would have been better to use the Prusa part downloaded directly from their site. I also experimented with adding a gopro type mount on the side. Eventually I discovered how to install a momentary on push button instead of using the trigger (because the trigger push was too short and required too much force). This design did work, but it's not ideal. P1 the Mount is mounted on the Left side of the X-axis over the motor. P2 is the bracket that theoretically could be attached behind the motor to secure it. I never used it, because wire ties worked well enough. P3 is the attachment to go in the slot. It has various size holes because I wasn't quite sure what my momentary switch was going to be, so the variety of holes made it easy to switch out. Once installed, it did trigger a timelapse. The G code essentially moved the extruder off the print to a point near the button, then left into the button then right off the button and then resumed. I originally messed with trying to control the extrusion, but that made more of a mess than it was worth. I'm also printing through a reel of ABS and that's not helping. So in conclusion, it worked, and could be a decent starting point for someone else, but having done it once, I could tell that the right side was a more suitable location. I decided to redo this with the mount on the Right side of the x-axis, over the idler, and I'll post that design separately.
