<p>This is the “GR2” rubber grommet that along with a metal bushing and a screw, keeps the PGM-III unit in place.&nbsp;</p><p>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.&nbsp;</p><p><i>Please, tune your printer with the below settings for optimal results :&nbsp;</i></p><p><strong>Plater :&nbsp;</strong></p><p>Print Settings : 0.15mm Quality</p><p>Filament : SainSmart TPU</p><p>Supports : Everywhere&nbsp;</p><p>Infill : 10%&nbsp;</p><p><strong>Layers and Perimeters :&nbsp;</strong></p><p>Perimeters : 1&nbsp;</p><p>Solid layers, Top &amp; Bottom : 5 &amp; 4&nbsp;</p><p><strong>Infill :&nbsp;</strong></p><p>Top and Bottom fill pattern : Concentric</p><p>&nbsp;</p><blockquote><p><strong>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.&nbsp;</strong></p></blockquote><p><strong>TPU will stick extremely well to the PEI sheet, do NOT omit to use kapton tape or glue stick on the surface.</strong></p><p>Have fun&nbsp;</p><p>Nick &nbsp;</p><p><a href="https://www.2t-racelab.com/"><strong>2t-racelab.com</strong></a></p>
