Bagsnatcher - Freezer Food Bag Stand

My wife wanted a stand for filling freezer bags with home-made soups, curries and the like.  It had to be robust, stable and be able to be safely used hands-free.  It also needed to be able to accommodate a range of bag sizes and to fold flat for storage.  There are commercial versions but reviews suggest they are a bit flimsy and unstable.  The Boss likes this one a lot!

The photos show a red-topped bag containing 1 litre of water and a larger blue bag with 2 litres (the blue bag has a maximum capacity of almost 4-litres but that's too full for freezing).  Clearly the stand can be used for lighter duties too.

The base is 160mm in diameter for stability.  For my first print I created a cylindrical hollow and paused the print to add a 44mm x 7mm lead disc - just because I had some to hand however this is not essentiaI.  I have printed another without the weight for my son's family and it is also fine.  On that one I have added a few small indentations in the base to accommodate rubber feet.  These can be punched from thin rubber sheet (1.5mm) and glued in.  Again not essential but nice to have.  Both base design files are here.

Neither the upper nor lower arms are handed so print two of each. 

Print upper arm on its side with support beneath the slot.

Print lower arm on its back with channel upward; no support required.

Base requires support only in the two 6mm pivot holes.  The rubber feet recesses in the base don't need support - at least not on my Prusa.

I used PETG for all parts.

The lower arms should be installed into the base in the upright attitude (not leaned over).  Use a fine blunt blade; press the leg down into the base whilst sliding the pivot pin down the blade.  A spot of silicone lube or vaseline makes it really easy.

Any feedback welcome.  It would be good to see some “makes”.
