Introduction

Inspired by the Filament Spindle MK1 by makerbot and the Printable Horizontal Filament Spool by Spacexula, this provides a printable built-in filament management solution. Hopefully bringing an end to tangled messes and bizarre hanging contraptions!

Planned Features

• can either be attached to the Mendel frame or sit under it
• 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
• takes up less space and more stable than the similar in concept Mendel Feed Spool
• all cad files created using OpenSCAD

Parts

Printed Parts

So far the following parts have been optimized and converted to OpenSCAD...

Requires mendel.inc and mendel.conf from the Parameterized Mendel project.

Printed Image	CAD Image	OpenSCAD	STL	Description
		File:Spindle.scad		Common modules included by other scripts
		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

TODO

• order vitamins
• make some modifications to Printable Horizontal Filament Spool models (might need diagonal reinforcement?)
