Overview
This RepRap variant is designed to be produced in a FabLab, and yet to be sufficiently modular to produce using a variety of local manufacturing processes. It is rather unfriendly to the lone user in its present configuration, as it (a) will make use of all the available CNC-type devices in the workshop in parallel and (b) doesn't work yet. It sprang out of a 2-day session organised by User:VikOlliver and about a dozen hard-working volunteers at FabLab8 in Wellington, New Zealand. They are invited to add their names to the list when they find out about this page :)
Current Status
Electronics assembled but untested and in need of a rewiring - note that stepper motor STEP & DIR pins must not be longer than about 100mm.
X Axis being worked on. Using carriage from Simpleton prototype slightly hacked by a nice lady at Fab8nz. To use NEMA17 and 3 x 608 bearings as corner pulleys. Tension in belt will draw underconstrained Z sliders onto Z guide rods.
Y axis fully assembled, bar the zero switch. Uses 5mm zip ties in the frame to hold both NEMA17 drive motor and the idler.
Z Axis partly assembled. Sockets for 608 bearings were not deep enough, the waterjet cut holes in the frame to support Z brackets need to be +0.5mm diameter. The Z motor bracket needs to allow the motor to drop down an extra 3mm to mesh properly with the large driven gear.
The deposition bed is a simple piece of plastic sheet stuck down with double-sided foam, so it needs no fancy holes. Y carriage is in 2 identical parts joined with M8 rod. Y belt secured to carriage with zip ties, which also tension it.

Basic Rules of Enagement
Any rules or warnings that should be established before using the Rroofl can be included here. For example, a safety related tip would definitely make a good addition to this section (thanks for the reminder, OHM).
- Do touch, but touch responsibly.
Ongoing Development
There should be some more information here...
