Ender 3 Max Neo - Hotend cover and Pen Plotter

thingiverse

This is a custom designed hotend cover/fan cover with detachable plotter attachment. I wanted to add a pen plotter holder to my printer and this was a good simple way to add the pen plotter. Designed for PILOT Precise V5 or PILOT Precise V7 rollerball pens. I have had the best pen plotter results with these pens. Other ballpoint pens would skip fine detail lines. Included for download are the Fusion 360 archive files and step files for customization. Front and side panels are fully customizable. For the cover: There is very little infill and higher infill will produce a better print and more material for the rear heatset insert. For my printer the difference between 20% infill and 100% infill is only 15 minutes. I highly recommend lowing the print speed for the first layer considerably do to the details on what is the front of the cover On my printer, print time ranged between 6 hours on .20 and 7.5 hours on .16 both with 100% infill and tree supports. For the pen holder: Standard print settings with supports will produce good results. Should work fine on all Ender 3 "Neo" printers. UPDATED - Added a second hotend design with less detail for prints less likely to have issues. For optimal installation the following hardware is required 1@ M3 heatset insert - for rear mount screw 1@ M2 heatset insert - for plotter lock tab 1@ M2X6mm - for plotter lock tab 1@ M3X20mm - for pen plotter "clamp" 1@ M3 Nut - for pen plotter "clamp"
