I use the bottle holder with a counter pressure bottling wand. It keeps the bottles standing during filling. Fits swing top bottles with up to 7 cm diameter (0.33 and 0.5 L).
I printed in PLA, 15% infill is sufficient, no supports required. The included rubber pads I printed in flexible filament (Recreus filaflex A82), this keeps the holder from slipping on the counter top.
The author marked this model as their own original creation.
