Sharpie to fit Copic Air Adaptor

I developed this product when I finished the Sharpie Spray Pen.
It’s a one piece 3D printed attachment that fits the Copic Airbrush System. By inserting a Sharpie into the nozzle and pressing your fingers down on the wings the compressed air extracts the ink of the nib and creates a Sharpie Spray Pen.
This print is only available to purchase from Shapeways due to the complexity of the 3D print.
POWERFUL COMPRESSOR REQUIRED TO USE THIS PRODUCT

I think there is mileage in developing an adaptor that fits directly to a 6mm tube, this will omit the expensive Copic system. Give me a nudge if this is a product that you think is worth developing. Write in the comments below or contact me via social media etc.
