Brewing - Blow off Rig

Shareing my wide moouth mason jar blow off rig for when you Ferment and then cold crash your beer. It will capture the CO2 from fermenting and reuse it during cold crash.I printed at .16, but could be .2. Use PETG so its more food safe, although it never touches food. Have fun and happy brewing. Note: I added support to the two lids for the lower barb hole. Glue these in place once you remove support. Nothing else needs support.
