The SAE Prusa wiki page has a very convenient list of McMaster-Carr part numbers for those of us in the USA, but I haven't found a similar list for the metric model, so I tried putting one together in Google Docs. (I'm happy for this list to go into the wiki or elsewhere once it's been checked, but for the time being, I didn't want to mislead anybody.) Side-by-side SAE vs. Metric BOM I haven't put together a RepRap yet, so I used my best guesses from the Mendel parts list, but there are a few lines I haven't filled out yet. Has anyone gone through this exercise, and can you help me fill out the rest? Are there better parts to use than the ones I listed? So far the prices look pretty comparable for SAE vs. metric. I get $85.31 for SAE, and the metric parts will probably be in the mid-$90s. https://reprap.org/forum/read.php?1,77325,77325#msg-77325 Sat, 10 Oct 2026 19:19:46 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,77325,97440#msg-97440 https://reprap.org/forum/read.php?1,77325,97440#msg-97440 docs.google.com]]]> riboflavin General Sun, 11 Sep 2011 23:23:39 -0400 https://reprap.org/forum/read.php?1,77325,91276#msg-91276 https://reprap.org/forum/read.php?1,77325,91276#msg-91276 Hobbes20xx General Wed, 20 Jul 2011 00:37:13 -0400 https://reprap.org/forum/read.php?1,77325,91160#msg-91160 https://reprap.org/forum/read.php?1,77325,91160#msg-91160

I haven't updated my Google doc in a while, but for some reason I couldn't open it either. And just after typing that, it seems to be back online.

If you come up with a parts list from another supplier, post it somewhere online to save someone some effort.]]> TMaccius General Tue, 19 Jul 2011 05:12:46 -0400 https://reprap.org/forum/read.php?1,77325,91130#msg-91130 https://reprap.org/forum/read.php?1,77325,91130#msg-91130 AF7 General Tue, 19 Jul 2011 02:04:01 -0400 https://reprap.org/forum/read.php?1,77325,91129#msg-91129 https://reprap.org/forum/read.php?1,77325,91129#msg-91129 AF7 General Tue, 19 Jul 2011 02:02:34 -0400 https://reprap.org/forum/read.php?1,77325,78461#msg-78461 https://reprap.org/forum/read.php?1,77325,78461#msg-78461

Here are the differences I see between your list and the one I posted earlier:

* Your M3 x 10MM BOLT (MOTORS) (91290A144) is actually an M4. The wiki has 91290A115 for that part.
* Your 5/16" washers (91090A110) are slightly smaller than the wiki's (90126A030) and come in a smaller quantity (100 vs. 192) but at a slightly lower cost per box ($3.87 vs $4.17).
* Using the 6' rods (98914A030) in your list is more cost effective than using 3' rods (98841A030), both on a per-foot basis and because you get help on the cut list, so you save $3.14. I wonder what this does to the shipping.

Other parts:
* I didn't have zip ties (7130K12). Probably a good idea!
* I feel like you should be able to get cheaper stepper motors than $14.95, but there seems to be a general stepper motor shortage going on, so maybe that's the best available.
* The RAMPS DIY kit ($162) isn't too hard to put together. For the cost difference, someone who already had a decent soldering iron could pick up a few Adafruit kits to practice soldering on.]]> TMaccius General Sun, 20 Mar 2011 16:15:18 -0400 https://reprap.org/forum/read.php?1,77325,77527#msg-77527 https://reprap.org/forum/read.php?1,77325,77527#msg-77527 My breakdown.

This might help. Might be incomplete.]]> MrJohn General Sat, 19 Mar 2011 18:03:26 -0400 https://reprap.org/forum/read.php?1,77325,77325#msg-77325 https://reprap.org/forum/read.php?1,77325,77325#msg-77325 SAE Prusa wiki page has a very convenient list of McMaster-Carr part numbers for those of us in the USA, but I haven't found a similar list for the metric model, so I tried putting one together in Google Docs.
