How about some pictures of the finished tool ?
Well, there is a 3D printer thread elsewhere, but since I didn't start it here ...

Here's what a lot of mine produces - small N scale models for my n scale model railroad.
All of the items in the pic were 3d printed by me (I didn't make all the models though). Oil tank, wooden boxes, barrels, shipping containers, concrete barriers, and custom stencils for airbrushing logos - even the tiny ladder was 3D printed. It works very well for this application and saves a ton of money because the small models are sold at highway robbery prices.
I also like to improve the printer as a hobby in it's own right, because I enjoy tinkering with things like that.
