I wasn't satisfied with some bed leveling and retraction tests I downloaded, and also didn't want to go searching too hard for more, so I made these models to help dial in my print farm printers. 

Hopefully they can help you dial in and calibrate yours, too! 

I also included some models I have been using to test the properties of various filaments - a test bar and a test hook. 

I think that many people would be interested in and find utility in the data if more of us were able to test the strength of our preferred filaments and brands - and with a 3d printed hook or bar and a cheap weight scale, that invaluable insight can be ours relatively easily (and cheaply).

So please post your makes and let the world know how strong your favorite materials really are OR just share your awesome knowledge of dialing-in printers/how to make the printing process perfectly pleasurable!

Any feedback on the models is also highly appreciated. Happy printing!
