[chbot] Making 3D printers more affordable

[Michael Pearce]

We have a RapMan here at work that works well.... after we figured out
the quirknesses and modded the feeder path so it didn't jam.

Sadly the price went up when the parent company purchased Alibre as
well and started bundling it with the 3D printers.

Some photos of a couple of items I made for test can bee seen at:

Also has a video of it working.
