This is used in conjunction with some of Aderusha's DDD Wall Control components to make an easily printable and long lasting tape holder.
You need two of the file supplied, 4 equal lengths of 3/8" rod, and whatever of the Aderusha components you want. I would recommend just two 2x0 Flat Right, and two 2x0 Flat Left components.
You don't need to use aluminum rods, frankly, wooden dowels work fine.
The author remixed this model.
This model turns the original tape holder into a flat-printable tape holder that must be used with the DDD system.
