MK3s borescope holder

prusaprinters

This is pretty sketchy, partial mount for the Teslong USB Borescope. This scope outputs mjpg-compressed video, making it suitable for octoprint on low-powered systems. A better position for a borescope is off to the left side, but some non-stock extruder shrouds block this view. Credit for the design goes to Martin on the prusa forums: https://forum.prusaprinters.org/forum/original-prusa-i3-mk3s-mk3-user-mods-octoprint-enclosures-nozzles-.../has-anyone-mounted-a-borescope-to-the-extruder-carriage/#p86663 The borescope I'm using has much smaller diameter (5.34mm), and the mk3s appears to have nowhere near the clearance below the extruder wire bundle.

You'll need to make sure that the scope doesn't collide with the headbed wire cover during mesh calibration, and that the lowest edge of the camera clears the two heatbed posts used to align the magnetic buildplate. In order to install the scope in this location, I also needed to replace one M3 cap screw in the (r4) heatbed cover with a flathead equivalent, so that it doesn't stick up past the cover. I also added one extra (loose) ziptie between the top of the scope and the bottom of the extruder wires to help push the angle down a little. Even so, about 1/2 of the frame is filled up with heat block, and aiming it any lower causes collisions and failed mesh leveling.
