Sodastream bottle bottom V4.0

Replacement for the original Sodastream bottle-bottom. The original can break, making the bottle pratical unusable. With this new baseplate, one can continue to use the bottle, and add more stability as a bonus (will no longer tip-over when placed in the fridgedoor). Can be printed in PLA - no special settings. Use some hot-glue to attache to the Sodastream bottle (just like is done on the original).
