This is a test pattern optimized for small geometries and quickly getting to the features as it is shorter than the classic 3DBenchy (which is great in it's own well deserved right).

This has graduated overhangs, full overhangs all the way to horizontal. It also has small features and hole evaluations as well as a few wall thickness tests and more.

This is the pattern i use since it prints in about an hour for high quality print. Then after this looks good I move on to 3DBenchy which highlights other features this pattern lacks.

Hope you find this useful and if you are setup for it and inclined, feel free to leave much smaller gratuities than the minimum Thingiverse support by using my bitcoin address 1yKJcrkLE7RmsLmZPL3ku5PpazGzNmDSS or Ethereum address 0xbCCEf017Ff00215496A768fb0238893Edf7584B0 but no worries or expectations, key thing is you find this useful! Enjoy!

Thanks again and 'Keep On Printin'
