I care for children with nighttime antenatal feeding, which involves a pump with tubing.The tubing must be purged before placing the probe, it very often happens that I do not know where to put the tubing during the purging. And often the liquid flows either on the foot, or on the ground. I also have 2 children in the same room having a pump. For ease, I created a support to clip onto the foot in order to put the probe or the tubing in the support and thus have my hands free during purging or others. I can not do without it. Compatible with all tubing or probe.I printed it in ABS for extra strength, then I soaked it in acetone for a smooth finish and no friction on the foot.The diameter of the pomegranate foot is 16 mm.Take a look at my profile to find other things.THANKS.
