It took me years to gather up the courage to buy one, in a moment of weakness I grabbed one at good price.

Useful? I don't know about that yet, but a large part of my motivation for getting this was how much plastic stuff we throw away when it breaks. And it breaks because its made poorly.

I would like to be able to break that plastic down, and create filament for the printer from it.
Print parts for a home made CNC machine (plastic and hardwood, not metal)
Make another 3d printer!
Make a LARGE 3d printer!
Print parts to fix stuff that breaks, so I don't add to plastic in the landfill

Basically print anything I will find useful, ultimately from plastic I have recycled, this is one step in a long journey!

Thanks for replying.

I've been to meetings of a local maker group where I first saw a 3d printer in action. I think it could be worth finding others who are interested to combine your skills. If you get designers, craftspeople, coders and others together some cool projects could come out of it.
