This is a remix of the Magigoo mount by Jubelsalami. There are 3 versions, a version in the orignal style that holds 6 bottles as well as a 4 bottle and 6 bottle version that attach to a flat surface such as on the side of a LACK rack. You can use No. 7 countersunk wood screws or smaller.

The original model can be found here: https://www.thingiverse.com/thing:3516604
