Hydraulic Ram Release Knob

So, I do a lot of projects in the garage that require the use of hydraulic rams, jacks, and engine hoists, and always find myself spending way too much time hunting down the stupid jack/ram handle to release the pressure. To make my life easier, I created these knobs to install over the release valves to minimize the amount of time I spend looking for the stupid handles.

There are two knob designs here for two different style releases: a round style (approximately .360" round w/ .155" T-rod) and notch style (approximately .375" x .270" w/ .155" T-rod). The notch style is confirmed to fit Harbor Freight Long Ram Hydraulic Jack P/N 56215, and the round style is confirmed to fit Harbor Freight 2-ton Folding Engine Hoist P/N 69514, but would be expected to work with most pressure release valves with the approximate measurements listed above. Note that the T-rod must be close to straight in order for the handle to fit properly.
