Prop for InSinkErator Filtered Water Faucet

We have an under-sink water filter and occasionally want to fill large jugs from it. The tap, an InSinkErator F-HC1100, is spring-loaded, so it must be manually held on for the minutes that this takes. Due to the sleek, tapered design of the faucet, it is nearly impossible to prop it open with typical household implements. (Our previous solution involved a chunk of lumber heavy enough to hold the faucet open. Its placement was precarious, so it would typically fall out of place unless further braced by a heavy jar positioned on the counter.)

I designed (FreeCAD) and printed this solution. It works wonderfully!

I printed this on a Prusa Mini using a 0.4 mm nozzle and 0.15 mm layer height (0.2 mm first layer). I printed it in Jessie PLA ("Vanilla Bean Ice Cream" color).  The parameters should not be critical (except that the magnet holes are designed with those specific layer heights in mind). It prints without supports.

There are three printed-in, 6 mm x 2.2 mm magnets (Amazon link) so that it can be stored on a refrigerator, microwave oven, etc. Pause the print at z = 2.75 mm to insert the magnets.

The STEP file, PrusaSlicer project file, and the GCODE file include designed-in mouse-ears for bed adhesion.  In the STEP and project files, these are included as separate parts, so you can easily disable or delete them if you don't think they're necessary.

The model includes grooves to attract the perimeter seams. Due to the sharp corners in the tiny grooves, most slicers should automatically place the seams in these grooves. (This is designed to be printed with normal butt — not scarf — joints.)

The STEP and STL files are upside-down (sorry).  Flip them for printing.

If you'd like any minor modifications made (e.g. different magnet dimensions, no seam grooves, etc.), or if you'd like the FreeCAD file, let me know.  Happy to help.
