ptfe tube holder

This mod helps keep the tube paralleled to the z carriage. Made this adapter for 3 mm diameter ptfe tube and an extra one for a 4 mm tube...hole sized at extra .5 mm so tube has no problem going in..glue tube in place and also ad a filter to catch most if not all the dust from filament , or double sided tape wedged around tube to wedge hold in the mount..i used some 5 minute resin and hardener mix..make sure the adhesive does not block or touch near or in the tube or it may create friction and prevent filament from sliding freely..the open space allows me to place a small square piece of filter to prevent dust from going into the tube itself, should work for the most part can be replaced with whatever type of filter you like as long as it fits in the spot like that one...
