Ender 3 v3 KE ploter adapter / penholder

After searching for a while and failing to find pen adapter i created my own. Inspired by the stright lines an the ability to to make copys of the same drawing my adventure started with a lot of frustration when trying to make the printer draw. here is the solution:

The way I do it

1- Find/Draw an image and vectorize it

     You can use whatever you want to make the image 2 colors and to be able to export it as .SVG

2- Use the SVG file to make an STL

     Using online tools or another way(please share if you have offline alternative)

3- import the STL in the slicer

     When slicing make the thickness 0.20 or a single layer.

     Set the flow to 0.0001% or the lowest possible and remove the filament.

     bed temperature to 0 and nozzle temp too (Problem 1)

     turn off all the fans and cooling

     set the z hop to enable if not and to 1-2 mm.

4- Using the adapter:

    Print 2 pices of the lower adapter and glue one of them to the pen you are using. that way the pen will not slide down when the printer does the zhop. the second lower adapret is placed in the lower part of the holder. then you can put the pen and the top adapter.

NOTE: the adapter shoud be mounted before that using two M3x14 on the right side of the printhead.

Problem i encounterd:

1- The printer didnt want to start with extruder temp set to 0

     soution: in case of rooted printer add “min_extrude_temp:0” under the extruder section in          the printer.cfg file. in case of non rooted I kept the temp at 180 to be able to start, but is a risk at your own.

Parts:

     Main penholder

     Lower and Upper adapters  ( in the files is the 8.6 mm adapter made for my particular pen.        folow the same design ad make yours. the outside diameter is 11.8mm for the tolerance of          my printer. it shoud be able to keep the pen stable and free to move too.

     Top puller - at the top of the pen atached with rubberband to the penholder

      rubberband 

     two M3x14 screws

IMPORTANT: it is realy important to set and adjust the z-offcet correctly!!! keep in mind that you need to glue the adapter to be able to place it allways at the same place and keep the same results. measure and calibrate every time!

how to calibrate:

1- turn your buildplate upside down to be smooth.

2- place a pice of paper on top of it and tape it there (or clip it like in my case)

3- move the printhead to 0.2 and adjust the pressure of the pen using the z-offcet and move the printer in XY directions to check the pressure.

DONT GLUE THE PEN TOO LOW!! it shoud be 1-2 mm lower than the nozzle.

When you are confident enought with the drawing you are making, you can swap the pen with ploter cutting knife and try to cut vinyl and make some cool stickers too.

I hope i didnt miss something in the guide, please give feedback if so for me to fix it. 

thank you and happy drawing!
