WORK IN PROGRESS
This is a modification of Thing #393155 to use a Z stage supported by three leadscrews and two linear rails instead of a cantilevered Z stage.
There is extensive information provided in the Instructions section.

Updated 4 June 2015:
- Added spool-rod-holder-8mm.stl and spool-rod-holder-10mm.stl. These are models for a bolt-on part to hold an 8 or 10mm linear rod for supporting a filament spool. The rod is canted upwards at a slight angle to prevent the spool from walking off the rod. The OpenSCAD source file used to generate the holder is also supplied.
- Added spool-core-toybuilders.stl which is a spool core which fits in filament spools from Toybuilder Labs and other distributors of eSun filament. It accepts two 608 bearings and will then smoothly turn on a 8mm linear rod, particularly when supported by spool-rod-holder-8mm.stl. The OpenSCAD source file used to generate the spool core is also supplied.

Model is Cymon's Cthulhu, Thing #17000. Video done with Octoprint runnning on a Raspberry Pi B+ using Mark Walker's GPX-based plugin. (One second of video is 25 seconds printing time.)
Updated 16 Jan 2015:
- Modified the passthru hole near the stepper motor. It can now accommodate, if desired, a typical power cord grommet with integral strain relief. E.g., a Heyco 1857 or 1858.
Updated 15 Jan 2015:
- Added cut files for an electronics box mounted to the rear of the printer.
- Added an explanation of the electronics box to the Instructions.
Updated 12 Jan 2015:
- Note that I found a 8x25mm shoulder bolt and 698 bearings to work best for the idlers.
- Added a wiring pass thru hole to the lower Z stage plate for HBP wiring. Optional, but perhaps a little more tidy. Especially if a wire tie is also used.
Updated 9 Jan 2015:
- Added text in the Introduction section of the Instructions describing the 180 degree rotation of the HBP and extruder carriage.
Updated 8 Jan 2015:
- Comment that for my choice of parts, a 500 - 510mm frame height may work better.
- Updated, easier to print crossbar spacing templates.
- Expanded information on mounting the crossbar.
- Python script
plates-0.py for generating layouts.
