I printed this twice using a .6 nozzle and .2 layer height with 3 walls and 8% infill. It required just over 400g of filament, as measured on a scale after printing and assembly. I'd recommend cutting down the infill to 5% and you should be able to get under 400g.

A single STL file is provided. This contains all three parts for a single side of the dispenser. To make a complete unit you must print all three pieces, then print them again mirrored for the other side (this is a standard function in Cura and other slicers). You will also need 4 full size 4mm alignment pins from the original model, two alignment pins printed at 70% length, and four 135mm lengths of 5/16" or 4mm metal rod or wooden dowel to connect the two halves. I found a length of "music wire" at my local hardware store for $2.50 that is long enough with plenty left over. 135mm is the correct length for US sized cola and beer cans. If you have different sized cans, you'll need to adjust length accordingly.

Superglue all of the parts together, using the alignment pins to connect them. Then glue the two halves to each other using superglue and the music wire. This results in a relatively fast print using relatively little filament (for its size) at a fairly low cost, while being very strong.
