Filastruder Vertical Bottle Hopper

thingiverse

I have tried a few hoppers for my Filastruder and I found a very good one for vertical mounting is http://www.thingiverse.com/thing:455026 . I just needed to make a few modifications as follows: Hopper shoot: I wanted to use an empty coke bottle so I can see all the pellets inside. I changed the feeding tube with a gradual shape change into a suitable mounting - the bottle end sticks in there tight enough. It is made for a 1.25L coke bottle but you might try others. Also, I merged the Lower Part A and the Hopper Shoot from the original design I found that the Lower Part A was very weak at the thin edges from the feeding cavity. Joining the two parts fixed that. I also cut out a little of the inside guide that was just a bit long for the hole in my pipe. Lower Part B: I strengthened the part - just gave it some more thickness. Shoot Door: I really liked the door in the original design - being able to dump all the pellets in the shoot was quite useful. BUT... overnight whilst extruding some filament I had an unfortunate door moment. The pellets inside had obviously worked their way into an undesirable position due to the movement of the auger... AND... WELL... I'm still getting pellets out of the carpet. So, I modified the door with a little channel that can accommodate that marvel of modern engineering - a rubber band. Keeps the pellets where they need to be. Enjoy! EDIT 14/12/2015: Added photo of black hopper mounted on Filastruder. EDIT 24/1/2016: Added lid for 1.25L bottle where bottom is cut off.
