Christmas is a time for angles. Whether this is due to poor understanding of how certain words are spelled or because of some atheistic reason I can't even begin to fathom remains unclear.

This simple design is made a 42 degree angle with a practical hole for hanging in a Christmas tree; or for hanging on a spike, screw or string. How you use the hole is frankly none of my concern. Either you figure out a good use for it, or you don't, it's as simple as that. If you for any reason prefers an non-holy angle I've added a stl for that as well. While I can't quite see the point of non-holy angles far would it be from me to judge you for having a perverted preference that makes you prefer it. I think it's important to be judgement free.

Why is the angle 42 degrees? Well, as far as I understand it that is the only angle that is good and proper. 45 degrees is a bit of a cliché and 30 degrees... well that's just plain wrong. There is a theory that Douglas Addams, who was quite knowledgeable with computers at the time he wrote the hitchhikers guide to the Galaxy, used 42 because it, in ascii, equals * (star). The star is commonly used as a wildcard meaning "everything"; which could read that "the meaning of life, the universe, and everything" is in fact everything. In this specific case it indicates that the 42-degree angle could be interpreted as a star... and having stars in Christmas trees is a quite common thing to have... not actual stars of course... having a 3.955 × 10^30 kg hot ball of gas and plasma in your Christmas tree is an extreme fire hazard and should thus be avoided.

Print settings. This should be really simple to print. The hole is a titled square giving you 45 degree angles, which should be printable with most printers as long as you don't have extremely bad bed adhesion.
