Replacement battery door for Fitbit Zip

The Fitbit Zip has a poor quality battery door that breaks easily (particularly the little tabs that hold it in place). Mine finally became unusable. Fortunately now you can 3D print your own poor-quality battery door! The features on this are so small that you'll certainly need to do cleanup with an x-acto knife, and may need to get lucky for the tabs to come out at all. I made several versions attempting to improve this and get the dimensions more accurate, but the one I am using (and the one pictured) is the first print, heavily cleaned up with a knife. Printed at "high quality" on a Makerbot 2x in ABS. Despite the fiddling to get it in, it's now lasted me a few weeks.

I think that the dimensions are good in the model itself, so perhaps on a higher-end machine you can just print and zip.
