Fixing Extruder issues

I have been experiencing the same problems as everyone else with the teflon barrell coming out of the bracket. This seems to happne most when the nozzle hits the work piece and it is extrremelyt annoying especially half way through a build.

I finally decided to fix it once and for all. My solution was to make a stepped piece of teflon

with a larger diameter at the top 22mm, in the middle 16mm and a jubilee clip bit at the bottom 14mm.

This is then placed into a piece of MDF with a 22mm hole at the top with a 16 mm

hole at the bottom to stop the teflon escaping. The idea of the 14mm bottom bit is to get more grip on the threaded rod so tha that part does not come out.
