For when the standard size is just not enough! Just a bigger hopper for a vertically mounted Filastruder. I also extended the chute to give the required clearance. It comes in two versions, look to see which one you need. I need the short version for my Filastruder no. 787. (Still waiting for the replacements of defective parts to be sent back) I have not yet printed this version, so as always, all feedback is welcome!
