Ink pen Boot style for conductive ink pen plotter style 3D printer modification This design was made as part of a project to explore various Ink formulations for the conductive ink pen plotter style 3d printer (https://www.thingiverse.com/thing:5380951) set up and other information can be found there. Two additional parts not printed are a rubber tube used for holding the ink with spring like contact, and a wire used as contact pressure point when writing. Assembly should be simple, insert the rubber tube into the pen-boot-top, insert the wire into the top of the pen-boot-valve (heating wire can help) then insert the rubber tube on to the other end, then insert the rubber tube assembly into the pen-boot-body (cone side) and lightly screw in place, then tightly screw the pen-boot-point into the pen-boot-body(non-cone side). Care should be taken to provide an air tight fit between the pen-boot-valve and the pen-boot-point, sand paper or gritty toothpaste can be used to smooth the steps made by extruding layers. Activation of printing is done by using the weight of the device on the wire to internally move the pen-boot-valve away from the inside of the pen-boot-point so that the ink flows down the wire. other upgrades to this project: https://www.thingiverse.com/thing:5794737 https://www.thingiverse.com/thing:5794620
