This uses slightly more material but is less fragile than V1 and test prints proved that the supports were less difficult to remove than in the earliest model. -This version will also contain a 4x reel stacking feature so that all models can be stacked with 3 spiral reels and a top piece. +This version will also contain a 4x reel stacking feature so that all models can be stacked with 4 spiral reels and a top piece. That will give 200ft capacity to the 50ft model and 400ft capacity to the 100ft model. A stretch goal for this version is to make a 35mm spacer and spindle set so that movie film in the format can be processed in 100ft lengths.
