Yet another purge bin designed to collect waste material during 3D printing for A1 printer. It is equipped with magnets slots to attached to the printer. The bin posted here is what I printed:  180 mm long (140 from z-bar), 100+ mm wide, and 120 mm tall with a 1.2 mm wall thickness.   This STL fits 10x2 magnets.

I'm including the Fusion360 project (.f3d), for changing dimensions, backstop height, magnet size, wall thickness etc.  

If you are new to Fusion360 or CAD in general, don't worry, the project is fully parameterized so making a taller back stop is as easy as changing a number.   Fusion 360 has a free personal use license: Form: Personal Use (autodesk.com) 

Once project is loaded in fusion 360, go to Modify→Change Parameters:

Then play around with changing the numbers.  Remember, Undo (Ctrl-Z) is your friend if things get ‘out of whack’:

Here is an example of making the backstop 200mm high with a different side angle:

If you do make your own bin from this, I'd love to see pictures in comments.

Thanks, and happy printing
