Description:
My daughter bugged me to make this. There were only length extendable looms available on thingiverse. This allows length and width extensions. Photo shows 4 looms fitted together. STL file contains the 2 differently staggered parts needed. If it’s not quite what you were looking for then do your own:http://www.thingiverse
