Copic Pen Holder for Drawing Robot (Classic & Sketch compatible)

thingiverse

I've redesigned the original pen holder from @henryarnold's Drawing Robot to fit **Copic markers**. This version of the pen holder is compatible with Copic **Classic** and **Sketch** markers, but does also fit a wide variety of other markers that are too big for the standard holder. ### Required Hardware - 1x M3\*8 Screws (0.3 in) - 1x M3\*12 Screw (0.47 in) (optional) - 1x M3 Nut -- ### Additional, but Optional 3D Printed Parts - [slider.stl](https://www.thingiverse.com/thing:2349232/files) (optional) - [Metric_3_MM_Thumb_Screw_V4.stl](https://www.thingiverse.com/thing:2349232/files) (optional) -- ### Instructions The **Copic pen holder** fits on the standard slider, but since it's mounted with a M3\*8 screw (0.3 in) and M3 nut for better stability, you have to **clip off the tubular extrusion** that fits the mounting screw on the slider. It's not even essential to attach the standard pen holder, but you can chose to print another slider ([slider.stl](https://www.thingiverse.com/thing:2349232/files)), if you are uncomfortable with the idea.  You can either use the set screw from the standard pen holder to hold the marker in place, or additionally print another screw cap ([Metric_3_MM_Thumb_Screw_V4.stl](https://www.thingiverse.com/thing:2349232/files)) from the original Drawing Robot things collection and use it with another M3\*12 (0.47 in) screw. -- Please leave a feedback and if you like my creation a tip is also welcome. ;)
