Top spool holder
This page is divided in three sections:
Filament guide
You have here 3 options, depending on your enclosure.
A- Simple filament’s guide (PrusaBox)
Files in 0PB_Prusabox > 14B_Top_Spool_Holder:
14B_For_PB_simple_filament_guide
Assemble the filament guide to the top of the printer-box with 4 M3x6mm screws (screw heads on the outside). There is no need for nuts: this part of the printer-box will not be subject to any pressure.
B- Chimney filament’s guide
STL files in “14B_Top_Spool_Holder” folder:
ModularBox:
- 14B_For_MB_top_filament_guide_base
- and one of the top part you want: 14B_For_MB_top_filament_guide_xxx
PrusaBox:
- PB_filament_chimney_base
- and one the top part you want :PB_filament_door_top_xxxx
The filament chimney is assembled with 6 M3 screws and nuts.
Move the extruder to each side to make sure that the filament is moving correctly.
If not, make sure that:
- The filament is sliding freely in the PTFE tube
- The PTFE tube is only 1cm in the top part of the chimney.
C- No filament’s guide (ModularBox)
STL files in “14B_Top_Spool_Holder” folder:
- 14B_For_MB_top_filament_no_hole
If you don’t want to use any top spool holder, print this file to seal the top slot.
