|J-Head||Reprap-USA||.5mm Orifice||3mm Filament||$64.99 + Shipping|
Note: An adapter plate will need to be laser cut. Link Also, finishing nails can be used with the Greg's Wade Reloaded (for J-head) design. (No adapter plate required)
|Printrboard||Printrbot Store||$130 + Shipping|
|RAMPS||Ultimachine||$200 + Shipping|
- If ordering RAMPS, make sure to order with Mechanical Endstops w/ Wiring and Double Connectors.

|Ultimachine||$72.50 + $12.50 shipping||Lulzbot||$97.50 + Shipping||China||~$85|
I've tested the Chinese motors and the Ultimachine motors and they both work great. - Paul
I've not tested motors from Phidgets, but they may also work: Phidgets = $70.00 + shipping
Note: The Ultimachine motors come with connectors attached, so you don't have to crimp your own connectors. The connectors are just 4 pin .1" header connectors.

Pulleys and Belts
|Item||Part #||Source||Qty Required||unit price|
|GT2 Pulley||A 6D51M015DF0605||SDP-SI||2||$18.51|
|GT2 Belt (2218.00 mm)||A 6R51MB09060||SDP-SI||1||$11.95|
|GT2 Belt (1 foot or 304.8mm)||7959K21||McMaster Carr||8||$2.04|
|GT2 Pulley (16 teeth)||1375K35||McMaster Carr||2||$10.18|
Note: Metal pulleys are not necessary, but it seems like finding plastic pulleys with less than a .9" inch (required for Y axis) diameter is difficult. The small tooth count and fine pitch should mean higher resolution than the standard MXL belts.

The smooth rod needs to be M8 (for the LM8UU bushings), but the threaded rod can be 5/16ths or M8. Paul Brown has lots of 5/16ths rod and enough M8 drill rod for 2-3 printers. There is a chop saw at the space for cutting these. These rod lengths are for this print bed: Lasercut Print Bed
|Smooth or Threaded||Length||QTY||Notes|
|Smooth||332mm||2||X axis for 270mm apart bases|
|Smooth||250mm||2||Z axis, can be longer|
|Threaded||200mm||2||Leadscrews, can be longer|
|Threaded||305mm||4||Bases 270mm apart|

Paul Brown made a design for this, but it is too large for our lasercutter: Thingiverse Link
Ponoko.com will cut it for ~$15. CNC'ing this part would be preferred.
Cut this part from 1/4" tempered hardboard from Home Depot. (pick the flattest piece you can find)
Initially, we will not be using a heated bed. PLA plastic prints well without a heated bed (not ABS though). PLA sticks to Lexan very well, so a Lexan sheet will work for the print bed.
Paul Brown ordered several large PCB's on 3/15/11 and is hoping to mill them into heated beds. They will be very cheap, around ~$15.
Mike C has made a couple of heated beds using Prototyping Stripboard wired up as a large resistor Thingiverse Inspiration. Seems to work well - heats faster than a commercial bed and costs < $6 for an 8" X 8" bed. Using two 4" X 8" clad copper boards (not electroplated) from Veroboard (ordered through Amazon.com) is a good, cheap source. Andrew Falgout improved on the soldering technique by using stripped Cat 5 wire as a bridge across the end holes to aid in soldering without increasing the thickness of the solder joint.
Note: Glass will need to be placed on the heated bed. This can be 1/8th inch glass cut at a local glass store to 8.5"x8.5". It should only be a few dollars per piece. Cork sheet under the hot bed will improve efficiency.

Paul Brown is currently trying to arrange a group buy. Filament prices have recently increased from ~$60 for 5lbs to ~$100. We might still be able to get it for ~$10 per lb.
