3D printing a mitre box: Part 2
Follow-up: the mitre box I 3D printed yesterday was a total disaster. It looked great coming off the 3D printer, but was a little too flexible due to its height. This morning, I clamped the skirting board to the mitre box after measuring, started sawing and about thirty seconds later pieces started breaking off. Three things I learned:
- Don't use PLA for things that will be subject to outside forces – it's a bit too brittle and can snap off and break easily.
- Don't print things so that the grain of the print is in the same direction as the force that will be applied.
- Print things a bit thicker than what you think they need to be. They may take a bit longer to print, but at least you'll have a more useful print at the end.
