Various mechanical questions about Mendel I have a few questions about Mendel: * Is there a better supplier than McMaster Carr? * Can you use the extruder/skate bearings from the Makerbot website in Mendel? * Can you use a ballchain belt in Mendel? * Where's a good place to find 624 bearings? McMaster Carr charges SO MUCH for them! * Where can you find M5x20 or M4x20 Fender (Mudguard) washers? McMaster Carr only carries M10x20. * What's a good place to find NEMA 14/ NEMA 17 steppers on the cheap? The best I can find is the Makerbot store (NEMA 17 for ~$15) https://reprap.org/forum/read.php?14,28754,28754#msg-28754 Tue, 10 Mar 2026 15:28:01 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?14,28754,28785#msg-28785 Re: Various mechanical questions about Mendel https://reprap.org/forum/read.php?14,28754,28785#msg-28785 It also appears that Makerbot DOES have the cheapest steppers online. Awesome!
Oh, and one more question:

Is the Extruder Kit on the Makerbot store compatible with Mendel? (I.E, can I use those parts, plus a few printed ones, to build an extruder for Mendel)]]> ziplock Mechanics Mon, 19 Oct 2009 01:17:29 -0400 https://reprap.org/forum/read.php?14,28754,28776#msg-28776 Re: Various mechanical questions about Mendel https://reprap.org/forum/read.php?14,28754,28776#msg-28776 2) those are 608 bearings, so those should work for the 2 608's
3) I think they still need to be fabricated. Ask Vik.
4) www.vxb.com Buy them in 100 ct quantities and share with someone.
5) See #1. Given that M4 and #8 are dimensionally identical for clearance holes, this should work. A little small, but close. [www.mcmaster.com]
6) Makerbot is probably as cheap as you're going to get, but I'm not certain if it's standard footprint. [www.kelinginc.net] has some, but I haven't done the unit conversion to see if its got enough torque. Otherwise anaheim will be your option.]]> SOI Sentinel Mechanics Sun, 18 Oct 2009 22:09:42 -0400 https://reprap.org/forum/read.php?14,28754,28754#msg-28754 Various mechanical questions about Mendel https://reprap.org/forum/read.php?14,28754,28754#msg-28754
