A foldable, modular holder that keeps gallon-size Ziploc bags open hands-free - perfect for marinating meats and other outdoor cooking tasks.

Designed specifically for Ziploc brand 1-gallon slider bags (the kind with the plastic slider closure, commonly found at Costco). Other 1-gallon bags without a slider may also work and could have a slightly larger opening. If unsure, print Ziploc Hold Open Mouth model first to test the fit before printing the full set.

Key features:

- No supports required

- Foldable design for easy storage

- Modular assembly - if one part breaks, just reprint that piece

- Threaded nut connections for secure assembly

Print settings:

- Layer height: 0.12mm for the nuts (⚠️important - do not exceed 0.12mm or threads may not work; 0.2mm is confirmed not to work)

- Material: PETG or PLA both work well

Assembly notes:

- When assembling the vertical braces/arms, the completely flat side (the bed side) should face outward

- Binder clips or chip clips can be added to secure the bag to the mouthpiece for extra hold, though may not be necessary
