Mega Felt Marker Topper

cults3d

I was achieving excellent ink coverage, but I began experiencing severe issues with hard reversals that caused the marker shaft to rotate into position so that the z-stage couldn't move upward due to the Sharpies hitting the bot's ceiling. So, I extended the shaft's length at the bottom to clear the MK6 extruder stepper and fan with the lowest mounted Sharpie, which leaves the most room for vertical movement, and added a securing bracket that utilizes the MK6 top right M3 bolt to eliminate reversal torque movement. I imported the original STL file that Bryan Duxbury uploaded into SketchUp and made my modifications. Please let me know if you encounter any issues with printing or functionality. As you might guess, this was only tested on a factory MK6 setup, and I have no idea if previous extruder builds will work. This model was printed and used on: TOM # 4890 MK6+ 1.75mm .4 nozzle ABP with aluminum plate topper and titanium belt covered in kapton
