perfusion manifold clamp

apparently these clamps used in perfusion for their three port injection manifolds are a bit pricey. this 3d print is the opposite of pricey. and equivalent in function. the holes are meant for appropriate length 1/4 inch hex bolts for the two manifold clamp and 5/16 inch hex bolt for the pole clamp. I have more versions specifically sized for a 32mm pole and friction fit for our hospital's specific manifold but this one is the most universal.

the knobs were created using this design on thingiverse...

the knobs took a bit of trial and error for size as well as a bar clamp to get a really good friction fit.
