Filament Guide for 20x20 extrusion.

Filament Guide for 20x20 extrusion.

I had recently converted my ender 3 Pro with an inexpensive direct drive kit and noticed that the filament would unspool on the Roller Spool holder I was already using.  The addition of a filament guild to prevent this is based on the new Filament Guild on the Pruse Mark IV.

I didn't see any guilds I liked, and thought I could come up with something using Tinkercad.

There are 4 Versions, each uses the same base design of a Boll and socked that will hold a small piece of PTFE tube to help prevent the filament form over spooling.  I finally chose the 4th version as it put the guild closest to the spool and would not impede the movement if the printer was reaching it Maximum height on a print.

Version 3 and 4 will require the addition of 2 - M3x8 screws and 2 - 3MM T Nuts.  This give the most secure contention for the Guide.  Version 1 and 2 simply slide into the 20x20 extrusion, but tend to slide back and forth while printing.
