macalister cyclone with PVC pipes
thingiverse
Cyclone for MacAlister vacuum (fits air inlet and hose) Build with: - 110 PVC pipe - 50 PVC pipe internally - bucket, any bucket really - 3 or 4 mm screws ( you do you, 3mm screws sufficed for me) - some wood screws ( to screw in air inlet to 110 PVC pipe) i tested it and it fits pretty nice, I didn't have to glue it, though it should help with the vacuum. I didn't check weight in -> weight out, for me it suffices that I don't have to buy new overpriced vacuum bags for the vacuum :) The only thing I would test - I would verify if bigger hose would be better, the one included with the vacuum has really small diameter and it might limit the airflow more than it should. Designed in openscad, let me know in the comment if you would like to tweak it.
