I think filament is best purchased in bulk and the cost split. I would
suggest the space scrape together money for the filament and ask for
donations from anyone using it. Price it such that the donations would pay
for the filament and a slush fund for future repairs of the printers. At
least for common colors and materials like black pla.
Perhaps a filament extruder build would be something worth looking into?
Also an acetone vapor chamber for smoothing prints.
