ulletjes filament extruder

This is a remix of the Lyman / Mulier Filament Extruder V5.
I call it the ulletjes extruder.
Because I using it to make 3D printer filament from bottle caps (hdpe).
And in dutch we sometimes call bottle caps "ulletjes".
I was looking for a way to create inexpensive filament with recycled materials.
Also it was a cheap way to test my extruder and update him.
First I made my extruder and soon I came to the conclusion that I needed a way to control the filament control the thickness and roll
