This was my original idea for a spray pen that I developed from a plastic pipe. After testing on multiple pens including Copic and Crayola, I discovered that Sharpie worked the best. This is because of the shape of the tip and fibre material it’s produced from.
When I was at university studying for my Industrial Design degree, I was tasked with creating product illustrations.
I was trying to create a texture on a rendering by blowing the ink off the end of my marker pen.
This was a messy and inaccurate technique so I created my first spray pen out of a plastic pipe. With no means to pursue this product after university I shelved it.
Now with the arrival of 3D printing, I dusted off my sketch pad to rediscover my original idea. Several months later and lots of prototypes I’m just about ready to sell my idea.
I sell the Sharpie Spray Pen on Shapeways, SLS 3D Printing is still very expensive but the quality is superb.
To reduce the cost of my 3D prints, I produce them on my home 3D printer and sell them on eBay, check out my listings below.

To further develop this concept I think a bespoke marker pen needs to be created, similar to the blow pen currently for sale in the UK. This should be sold separately without the blow pen enclosure. Then an adaptor that fits directly to a compressor hose. The Copic Air Can adaptor is over complicated and it took me a while to all the attachments.
