Fox : a simple Guizmo to test any filament and make a collection of filament samples.
The Fox Guizmo makes a good print test too. All you want to see in a torture test, embed in one single model, pretty quick to be printed.
Fox Guizmo allow to check :
- Overhangs 40>63°
Don't expect perfect prints anytime. The Fox Guizmo is meant to reveal any filament issue. Some filaments are good for some purpose and rubbish on others.
It's a good thing to print your Fox Guizmo at the end of the spool, when you know the perfect print settings for that filament. Then you keep with the Fox Guizmo a sample of the filament, and write below the plate the type and print settings, for your collection. So when you're in search of a filament for a particular project or your next order, your collection will help you, your friend or a customer to make up your(his) mind.
How an idea leads to a fox...
You probably know the 3D benchy or Marvin. There's some dedicated tests (overhangs, bridges, temperature, etc.) and torture test too for your printer. Honestly, since the start I was in search of a simple model that prints quickly and covers all you want to check. After a few years searching, I started a filament collection with several unsatisfying models, but I did not find the graal.
So I started to assemble simple shapes together covering all the tests I wanted in a single piece. I wanted a large base to write filament type and settings then a bunch of planes, overhangs, holes, thin walls, details, and two little towers to reveal stringing on the top. The overall piece looks like a strange dog. I decided to refine the model to a recognizable shape. It ended to looks like a wolf or a fox, so I changed the details parts using font letters F and X with the M3 hole in between : FoX. Why not ?
