MK3S FS Cover with PTFE tube mount

thingiverse

This uses the original part made by Prusa Research, but with a PTFE tube holder added under GPLv3. No fitting is needed; this design utilizes a conical hole to grab the PTFE tube securely. Adding the PTFE tube helps prevent the X-axis from yanking on the heavy spool. This setup is identical to that used by Aleph Objects LulzBot TAZ 6. However, this modification is only necessary if you choose to relocate the filament spool away from its intended position above the z-axis. It can also be useful when combined with the SpannerHands Spool System. The following openSCAD code was added to the original file without altering anything else (except for the revision text): ``` module PTFE_Tube() { difference() { union () { translate([0,0,5]) cylinder(h=10,r=4,$fn = 60); } translate([0,0,4.9]) cylinder(h=11, r1=2, r2=2.2, $fn = 60); translate([0,0,13]) cylinder(h=4, r1=2, r2=4, $fn = 60); } } PTFE_Tube(); ```
