Duplicator i3: Top Mount Spool Adapter

This is an adapter to mount filament spools on the top of the printer frame. This is not as good a solution as using a filament guide tube. With my guide tube setup I am limited to around 150mm of print height. If I need more than 150mm I'll use this adapter instead of the guide tube.

Please note I did not design this. It is available for download here:

I added it to thingiverse because it is extremely hard to find on wanhaousa (no links to the page at all).

Printed with PLA @203C with 0.3mm layers @45mm/s. 20% infill and 3 outer shells. 4 layers on top/bottom. I had to slightly enlarge the holes on the steel bracket with a drill bit by hand to fit.
