44 oz Styrofoam Cup holder. Extended due to my rig having a high center console. It works very well. The holder is made so that as the cup is held tightly so not to spill but removes easliy. I have tested this with several cup manufacturers cups and so far all fit well.

I have created a larger size supressor holder. This holds the HUXWRX Flow supressors and is made to hang under a shelf with 2 #10 screws, not included :)
