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 perfectly. This modified version of the pen holder is compatible with both Copic Classic and Sketch markers, but it also accommodates a wide range of other large markers that won't fit in 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 mounts directly onto the standard slider, but for added stability, you'll need to secure it with a M3*8 screw and M3 nut. To do this, simply clip off the tubular extrusion on the slider that fits the mounting screw. You can also choose not to attach the original standard pen holder, or print another custom slider ([slider.stl](https://www.thingiverse.com/thing:2349232/files)) if you prefer.  To hold your marker in place, you can use either the set screw from the standard pen holder or print an additional screw cap ([Metric_3_MM_Thumb_Screw_V4.stl](https://www.thingiverse.com/thing:2349232/files)) and secure it with a M3*12 (0.47 in) screw. --- Please leave your feedback, and if you appreciate my creation, a tip is always welcome.
