flsun prusa i3 filament holder

I had a problem with the extruder's Teflon tube and I was forced to change from Bowden to Direct. I am waiting for the parts to repair and dismantle the Frankenstein's extruder. Meanwhile (surprisingly) the 3d printer works.

At the end I was able to design a filament holder that can be used with a 1/2" tube. The material requirements are low and It can be located at the top.
