Cupcake Upgrades

The venerable Cupcake is MakerBot Industries first 3D printer. Over the years a huge number of upgrades for it have been designed and posted on Thingiverse and around the web. This is a collection of the best and most important upgrades for your Cupcake to improve its performance and keep it running well.

Unless otherwise noted, I didn't come up with any of these upgrades . I'm just compiling them into one place.

I need your help! I don't own a Cupcake, so I created this list from perusing Thingiverse and the MBI forums. There are great upgrades out there that are missing because I don't know about them, and some of these might not be the best choice because I can't test them. Help out by letting me know what I am missing or should change
