About the job
This is a one-time personal project to design a compact, 3D-printable housing for the wireless sensor and attached battery assembly from a Canpump pressure-washer spray gun.
In the original gun, a magnet on the trigger activates the sensor, which wirelessly turns the pressure washer on and off. The system only supports one paired sensor, so I want to relocate that sensor to the pressure-washer hose near the tool-end quick-connect. This would allow me to use the same wireless control when switching between the spray gun, lance, surface cleaner, and other attachments.
The housing would contain the existing sensor, battery, and connecting wire. On top, I envision a manually operated sliding ON/OFF control with a small neodymium magnet underneath. In the ON position, the magnet would align with the sensor; in the OFF position, it would move far enough away to deactivate it. The slider should remain securely in either position and have clear ON/OFF markings.
The enclosure should be reasonably compact, durable, splash-resistant, serviceable, and designed for FDM printing with minimal supports. It could attach to the hose using hook-and-loop straps, a snap-on mount, or another simple method that will not damage the hose or interfere with the quick-connect. I am open to simpler or more practical design suggestions.

I have included photographs of the original gun, the sensor/battery assembly, and a concept image illustrating the general idea. The concept image is only a visual reference and does not represent exact dimensions or required construction.
I will provide accurate measurements and perform the test printing myself. Final deliverables should include the editable Fusion 360 file and print-ready STL/3MF files. The model does not need to be fully parametric, although it would be helpful if the magnet pocket and hose-mount diameter could be adjusted without rebuilding the entire design.
My maximum available budget is C$250. Please provide your best fixed-price quote; simpler and lower-cost proposals are welcome. I am looking for a practical design rather than a commercial product-development package.
