MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
Printed in PETG @.2mm for testing. I first printed the bottom (left) and the deeper notch version (right). I found the fit to be too loose just as you did. Printed again at your recommended 98.75% size (center) for the X and Y. The fit is great and much better than the default. Using PETG makes for a flexible and durable container while being slippery for smooth movements. I will be printing many more soon. Clear bases with solid tops to limit cheating though.
