Sharpie Holder For Ender 3

THIS IS A WORK IN PROGRESS.

CURRENT UPLOADED MODEL WORKS WITH MINOR MODIFICATION
-The width of the bracket is too small so you need to shave off the right hand (short wall) side to make it fit.
-Insert a piece of note card to create enough tension to keep bracket in place.

Overview
I was interested in a plotter mod that didn't need to be bolted or permantanly mounted to work. My design allows for a quick addition by just slipping on the extruder fan cover without any screws or bolts. As well the pen grip is tightened by a binder clip that I'd imagine everyone with a printer has. The hole fits a Sharpie.

Process
I extruded a text in Fusion 360 at .2mm height, or one printed layer, loaded the .stl in Cura and created a custom profile with all heated settings off, and all fans off. Enabled "Z Hop" at 2mm. Set print to 1 Wall and 0 Layers. I'm not sure how to offset the X and Y axises to move the nozzle location to the marker's location. Work in Progress. My printer has a BLT
