Release status: Experimental
A printable built-in filament management solution. Hopefully bringing an end to tangled messes and bizarre hanging contraptions!
Building on the work of these other designs.
Filament Spindle MK1 by makerbot
Printable Horizontal Filament Spool by Spacexula
Mendel Feed Spool by nicholasclewis
Perhaps adapt the partly printable spool from the Mendel Feed Spool or the spool used in Zaggo's filament box.
The end result will look similar to the base of this Mini-Mendel rendering by M.BrittCrane
- can either be attached to the bottom of the Mendel frame, sit under it, or sit beside it separately
- stackable for multiple spools and/or multiple extruder configurations
- can either feed directly into a normal extruder or provide a mounting spot for a bowden fed extruder motor
- all cad files created using OpenSCAD therefore parametric for easy modification
So far the following parts have been optimized and converted to OpenSCAD...
Requires mendel.inc and mendel.conf from the Parameterized Mendel project.

|File:Spindle-tube-fitting.scad||Defines shape of the tube fitting used by tube holder|
|File:Spindle-hub 1off.scad||File:Spindle-hub 1off.stl||Central hub with bearing that spool turns on|
|File:Spindle-tube-holder 1off.scad||File:Spindle-tube-holder 1off.stl||Uses an embedded tube fitting (same as MakerBot's) along with HDPE tube to feed filament through|
|File:Spindle-bearing-bracket 2off.scad||File:Spindle-bearing-bracket 2off.stl||Holds up half of the bearing rollers that the spool spins on (TODO: figure out why raftless skeinforge plugin seems to print entire first layer slowly instead of just the perimeter?)|
|File:Spindle-support-bearing-bracket 4off.scad||File:Spindle-support-bearing-bracket 4off.stl||Holds up half of the bearing rollers that the spool spins on as well as 2 cross bearing rods top and bottom|
|File:Spindle-corner-bracket 8off.scad||File:Spindle-corner-bracket 8off.stl||corners, double holes so that the same model can be used on all 4 or 8 corners|
|File:Spindle-spool-spoke 4off.scad||File:Spindle-spool-spoke 4off.stl||attaches to the bottom wooden circle for a partially printed spool|
|File:Spindle-spool-hub 1off.scad||File:Spindle-spool-hub 1off.stl||attaches to the top wooden circle for a partially printed spool for spokes to snap into for easy removal|

order vitaminsvitamins arrived and seem to be correct
- make some modifications to Printable Horizontal Filament Spool models (might need diagonal reinforcement?)
- figure out proper dimensions and most efficient way to cut 1m rods
- figure out a logical way to attach to bottom of Mendel frame
