Prusa LACK Enclosure Filament Roller Guides

mrtamer's filament roller guide was a perfect solution for what I needed. I however was not wall mounting these, and instead used them with my LACK enclosure which was having some issues with filament snagging when running the filament into the case. These were almost perfect for solving the problem, with just a few minor adjustments.

I rotated the holder 90 degrees and created a specific base and holder for my Prusa i3. I also created a version of the holders with a dome wrapped around the exterior to ensure the filament stays on the guide, but for some applications that may not be necessary. The holders and runners had a slight reduction in their width as well.

Instead of using normal 608 bearing for this, i also use the 608 print-in-place bearings by guppyk. I felt it was a bit of a waste of ball bearings for this specific application, however after a bit of synthetic lubricant guppyk's print-in-place bearing work perfectly and roll just enough for my application to help prevent any more snagging.

For the Prusa Mounted Piece I modified the thing from fardog moving the connector piece more to the center and adapting it to work with the holder.

Using 3 of these solved my snagging issues perfectly. Below is a list of the parts and quantities I printed for my case.

• Base.stl (x2)
• Prusa_Base.stl (x1)
• Bearing_Print-in-Place.stl (x3) (optional if you are using 608 ball bearings)
• Runner.stl (x3)
• Horizontal_Holder_With_Dome.stl (x2) (could use Horizontal_Holder.stl if you do not want the dome)
• Prusa_Holder_With_Dome.stl (x1) (could use Prusa_Holder.stl if you do not want the dome)
• Bolt.stl (x3)
• Nut.stl (x3)

I will update with picture of my setup once I have a moment to get some.
