Prusa i3 Property "Tool Image" (as page type) with input value "File:" contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process.

{{#if:No | [[Tool Owner::{{{ProjectParticipants}}} | }} {{#if:No | [[Tool Cost:: | }}

So, it seems we are going to be build 3 Prusa I3 printers sometime in the future.

This page is an attempt to document it all, our own little BOM. (bill of materials)

Meh, moneytrain is slow ....

In other news, http://www.rrd.bz/ has (unasked) sponsored us with a Rumba incl 6 stepperdrivers, 3 Pulleys of unknown size and a cable set.

--buZz (talk) 14:40, 16 April 2013 (CEST)

FINALLY TOMORROW we are going to order moar parts :D

Belts & Pulleys;

• 8 times http://www.ebay.nl/itm/T2-5-Alum-Timing-Pulley-5mm-shaft-16-tooth-for-RepRap-Prusa-Mendel-Huxley-CNC-/280991346649
• about 12 meters http://www.ebay.nl/itm/T2-5-Timing-Belt-6mm-perfect-for-RepRap-Prusa-Mendel-Huxley-CNC-Best-deal-/271168041672

Bearings;

• 4 times http://www.ebay.nl/itm/10pcs-LM8UU-8mm-Linear-Ball-Bearing-Bush-Bushing-/370725908447
• 1, or 2 times http://www.ebay.nl/itm/2pcs-LM8UUOP-8mm-Open-Linear-Ball-Bearing-/370728172771
• 1 time http://www.ebay.nl/itm/10pcs-625-ZZ-Miniature-Bearings-ball-Mini-bearing-5-x-16-x-5mm-/390366399952

And maybe 5 moar motors for TallOak? :) Oh! and a load of plastic :D

--buZz (talk) 00:51, 29 March 2013 (CET)

So I've started printing parts, first 3 sets, but now maybe 4...

Also, i've bought the spare motorstock from the0, 10 pieces of Wantai motors for 100. We still need 5 extra (Dupe doesn't need motors)

And we got a 4pi from Kliment (and some 624 bearings) for 100 euro. This is ment for the Fablab.

Regarding smooth rods, it seems profzon could still deliver them but is way too busy to do so now, so we will have to look elsewhere. He _is_ able to provide the M5 threaded rod and M8 nuts&bults and will do so ~quickly

Needed

power supply

Currently i am using a 12V supply for everything, but it is quite possible to heat the bed on 24V and run the motors on 12V. Maybe

• http://www.ebay.nl/itm/DC-30A-12V-Regulated-Switching-Power-Supply-Universal-360W-Free-shipping-New-/360565787697

40 euro

hotend

I don't see any reason to not use a J-Head.. 0.5 is fast but i might follow ID and profzon and go for 0.4..

• http://reprapsource.com/en/show/6752
• http://www.ebay.co.uk/itm/261163729498?var=560181572300&ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649

No idea yet.. Maybe go for 4pi?

• http://xyzprinters.com/electronics/177-4pi-3d-printer-controller.html

Or this thingy for cheapness?

• http://reprapworld.com/?products_details&products_id=327&cPath=1591_1606

stepper drivers

Provided we are _not_ going for 4pi, we need some. Stepsticks should be fine.

• http://reprapworld.com/?products_details&products_id=35&cPath=1591_1599
• http://dx.com/p/stepstick-a4988-stepper-motor-driver-module-white-black-186465

stepper motors

They cut us a deal earlier, maybe we can try it again?

• http://reprapworld.com/?products_details&products_id=94&cPath=1614

55 euro

smooth rods

Not sure, maybe profzon has an idea about this?

Stainless: http://www.fnf-metaal.nl/roestvaststaal/leveringsprogramma/rvs-staf http://www.rvsland.nl/Webwinkel-Product-5856865/Staf-RVS304-%C3%98-8-mm-H9.html

Typically ~3 EUR per metre. ~3m per printer (not including inefficiencies etc.) ~10-15 EUR. TallOak (talk) 15:09, 29 January 2013 (CET)

20 euro

threaded rods

We have a shitload of M8 threaded rod on the space already, we _will_ probably need to get ~5 meter of M5 rod.

10 euro

nuts & bolts

Again, not sure... profzon?

10 euro

bed heating

I would like to maybe experiment with a different sized bed, seeing as this is available for not much more money.
