Pen Holder for Ender 3 / Ender 3 pro/CR 10/Ender 5

Using this attachment, you can attach a pen or marker to your ender 3 or ender 3 pro or cr 10 or ender 5. Using this attachment requires removing the hotend assembly. Print this instead https://www.thingiverse.com/thing:4574948 if you do not want to remove the hotend assembly. Print only pen_direct_attachment.stl and bolt.stl for standalone operation If you want a sliding mechanism that can actuate up and down, print back_part.stl, pen_part.stl and bolt.stl. This will require additional 4x M3 screws, 8x M3 nuts and 4x small v groove bearings with 12mm outer diameter and 3mm hole. I am also including the Fusion 360 project if you want to make a remix easily. To generate GCODE for drawing anything, I have created an Inkscape extension which you can see here https://invensphere.com/draw-3d-inkscape-extension-setup/ To see my new designs, like my facebook page https://www.facebook.com/UmersLaboratory/ I can not receive tips here since PayPal doesn't work in my country. You can donate on patreon instead https://www.patreon.com/umer . Thanks.
