We are makers at heart here at MakerGeeks.com so we really like parts... I mean, like really... maybe just a little too much at times but nothing is worse than needing a spare part and not having it or not being able to find one. So, we try to stock and source as much of what you'll need to build a 3D printer, fix a 3D printer or just stock-up the work bench with geeky goodies!
Enjoy and make sure you drop me an email if you need something that we don't have... I bet I can get it for you QUICK! My email is firstname.lastname@example.org.
