Introduction

Nylon is a strong and impact-resistant thermoplastic that is used

If you ended up here, I think you likely got an error like what is pictured above. For some reason your avr-gcc library doesn't include the header files for the ATTiny1608 or ATTiny808 processors. But the good news is you can just download a few files (like from here) drop them in the right place and then everything will work.

	/// Chamfering OpenSCAD Example
	/// Written by Robert Quattlebaum, 2022-12-14
	///
	/// This example shows a method for adding a chamfer to a certain
	/// class of 3D objects where the profile in the Z dimension doesn't
	/// change significantly.
	///
	/// You must specify the size of the chamfer, the height of the child
	/// and the Z-offset for the bottom of the object. You can also specify
	/// the shape of the chamfer, which can be either "cone", "curve", "curve-in",

	# Use like:
	#
	# ```
	# openssl req -x509 -nodes \
	# -days 3650 \
	# -newkey rsa:2048 \
	# -keyout /etc/ssl/private/host.key.pem \
	# -out /etc/ssl/certs/host.crt.pem \
	# -config self-signed-cert.cfg
	# ```
