You know that burning sensation, the one where you dump crunchy granules of fertilizer all over yourself after the spreader explodes? Yeah, that one. What to do? You’re stuck because you want to finish feeding the nitrogen-depleted grass blades, but can’t. Your afternoon plans have been foiled yet again. Well, there’s no better time to dust off that ol’ 3D printer catalog and start looking for some plastic-layering power to make sure that this never. happens. AGAIN.

Excuse for Buying a 3D Printer?

In this case, we have a broken crankshaft – the shaft sheered right in two. Now, you could just look through your garage/shed or head down to the hardware store to find some simple parts to repair your broken item, but that would make WAY too much sense and be way too practical. Instead, feed that inner geek ad first, head over to a place like GrabCAD to see if any other unfortunate soul had the same thing happen to them, and has already modeled and uploaded the part you need. If that doesn’t work, fire up the old 3D CAD program and model the offending part, making sure to take into account your 3D printer’s capabilities and limitations. Then, print, fix, and away you go!

Why manufacturers do not provide an .stl of their parts or an option to print and deliver a new part is beyond me. When are we going to get there?
