Weed Sprayer Wrench for CHAPIN model

This wrench can be used to unscrew the pump from the CHAPIN model weed sprayer (this style: https://www.amazon.com/dp/B000E28UQU). The Parts The parts are made for partial compression fit. The prongs are separate so that you can print them with the layer lines perpendicular to the wrench, otherwise during use the layer lines would be in the axis of torque - more likely to break at the layer lines. The "keeper" is so that you can print using something like PLA, and use more torque without breaking the wrench. Not required to use, but if you need it. Notable Print Settings I found using PLA these worked well - Wall count: 5 - Infill: 40% cubic infill

Why? Normally there are two nubs on the shaft of the pump fixture that when the handle is fully down, it allows for using the handle to screw and unscrew the pump. But those two nubs easily sheer off. This custom wrench allows for inserting into the sockets where the nubs normally do, so that the weed sprayer can continue to be used.
