This is the “GR2” rubber grommet that along with a metal bushing and a screw, keeps the PGM-III unit in place.
A suitable material for the application is TPU (thermoplastic polyurethane), a flexible filament with excellent vibration-damping properties, high toughness and chemical resistance. The grommet will be a little bit stiffer than the OEM part, so if you wish you can use TPE filament instead.
Please, tune your printer with the below settings for optimal results :
Plater :
Print Settings : 0.15mm Quality
Filament : SainSmart TPU
Supports : Everywhere
Infill : 10%
Layers and Perimeters :
Perimeters : 1
Solid layers, Top & Bottom : 5 & 4
Infill :
Top and Bottom fill pattern : Concentric
It is also possible to print the grommet on its side with a small portion chopped off, as to provide a flat print surface and NO supports.
TPU will stick extremely well to the PEI sheet, do NOT omit to use kapton tape or glue stick on the surface.
Have fun
