Makerbot Button Holder
thingiverse
This is a nice little button holder that will let you install a button in the existing holes on the top of the TOM. Saves drilling and adding more holes to your Makerbot. Instructions Print and install. You may need to adjust the hole diameter to accommodate for your button. Mine required a 16mm hole. In my case I had an interference fit to keep it in place as the fastening nut that came with the button wouldn't quite fit. When the button is installed in the holder all you need do is snap it into any of the holes on the top of your TOM that you have free. The little tabs work great and allow easy removal if required.
