This is an IV pole mounted card holder for keeping quick notes such as initial vitals, warnings, whatever. It is designed to hold inexpensive plastic ID card stock. I recommend a wet erase marker be used, dry erase is too easily accidentally removed. Depending on the diameter of your IV pole, you may need to alter the C clip in the design. This clip is for poles around 11-12mm diameter.  The photo shows this being used with some syringe holders of my design that I have listed separately. I recommend using PETG, at least for the C clip.  PLA is too brittle. I have tested this out in my rifle scope mounted DOPE card version.
