Dyson DC07 DC14 HEPA filter shim FIXES SQUEAK

The “Lifetime” HEPA filter on my Dyson DC14 was driving me insane with all this squeaking!  The gasket has aged and lost enough elasticity to keep a tight seal, and was letting air squeak around it like a reed.  This simple 1mm tall shim was all it took to get the filter tight enough to stay sealed!  You can scale it up in the Z axis if your gasket needs more help than mine.  I printed this with 0.2mm layer height out of PLA.  I used the Archimedean spiral for the Top and bottom faces, as well as the internal solid infill which really cut down on print times.  1 Perimeter, the rest was solid internal infill.
