    Just saw this on Hack a Day:

    http://us.misumi-ec.com/news/topics/2014/01/misumi-first-150-promotion-terms-and-conditions.html

    Might be worth seeing if we could get some of our parts at a discount…

    Here is the quote I got for the hardware parts for the Reprap Prusa i3 http://reprap.org/wiki/Prusa_i3_Rework_Bill_of_materials

    The total is 279.59. Let me know who wants to split the order with me so that we can get it all free + shipping. We could have most of the material by the open house if we order soon.

    I think this is all of the hardware with the exception of the threaded rod. We would need a sheet of something for a frame, the electronics, steppers, extruder, heated bed, and 3D printed parts to make a full printer.

    Unfortunately it looks like it won’t ship till the 25th, so not in time for the open house.

    Someone else needs to buy the rest now!

    To make it easy for whoever else wants to order, here is the remaining shopping list that needs to be ordered. Load it up with filler items (alum extrusion or whatever) to get as close to $150 as you can.

    I am putting in an order for the last half of that Prusa build!

    Thanks for taking the time and effort to break the list apart!

    Alright, that last order has been submitted! Now if someone wants to get some stepper motors (nema 17′s will probably do okay), that’d be great!

    Awesome! I’m looking forward to seeing what everyone else is able to get.

    i’m dumb so tell me exactly what we want and i’ll order.

    I think you can’t go wrong with a bunch of aluminum extrusion, brackets, and screws. Might want to check with Jim or Tim to see if they have suggestions on particular sizes or shapes that would be best.

    Might be cool to get some raw blocks/sheets of aluminum, delrin, etc. too.

    If anyone is looking for stepper motors, this part HT17-275 would probably be good enough for a 3D printer (or even a small desktop mill). Its the highest torque low impedence NEMA 17 sized stepper motor they carry.

    Going for $53.00 a piece which is really expensive for that type of motor but you can basically get 3 for free with this current deal going on…
