Not only can the Makerbot print its own upgrades. But these upgrades really improve the print quality. A virtuous cycle!
At this point my MakerBot TOM is finely tuned and making beautiful prints.
Here are all the upgrades I have installed:
Y-Axis Idler Support Bracket for Thing-O-Matic: This stabilizes the Y-axis idler.
Easy Install Thing-O-Matic Universal X & Y Axis Belt Tensioner: This is the single most important upgrade. The belt must be correctly tensioned for good prints!
HBP Quick Leveler Redux: Another essential upgrade to easily level the build platform.
Thing-O-Matic Electronics Side-Mount: At some point you will need to tweak the electronics. This mod makes it easier.
Thingomatic y-axis Endcaps: These endcaps make it easier to remove the Y-axis rods.
MakerBot Cable Clip: Nice clips for cable management.
Simple Tool Holder: Organize all the hex wrenches that come with your MakerBot.
I purchase two upgrades from MakerBot that are well worth it:
Aluminum Build Surface: This gives you nice flat and level prints. Seems like this should be included with the Thing-O-Matic!
MakerBot® Gen 4 Interface Board Kit v1.1: This allows you to run your MakerBot without a computer attached.
