KNK Zing Orbit Fine Point Sharpie Holder

thingiverse

I created a fine point sharpie pen holder for my wife's Zing Orbit. She has the 24inch wide version, and I assume the tool head would be similar on smaller ones. The holder features two indents that should align with the thumb screws on the KNK's tool holder for repeat-ability purposes. This ensures that you can remove the tool and re-install it without having to guess its position each time. Additionally, there is a hole for drilling and tapping an M4 screw, which secures the Sharpie to the holder. I used an M4x25 bolt that was lying around. Note: When printing this design on my UM2+, I needed to scale the X and Y axes to 104% to achieve a correct fit due to shrinkage. PLA material worked well for me. You might need to print it multiple times until you get a snug fit for the marker, similar to the pen cap - not too tight but not too loose. I tested this design at a speed of 16 and pressure of 120, but these settings are just a starting point and may not be optimized for the best results.
