Dash panel gromet (Toyota?)

Dash panel(Suzuki or Toyota mid 90s I think, I was only given the part to copy) plastic pop-in gromet, this probably needs a bigger cube for longer pop-in ears as this was not a tight fit, I should probably have also made it solid rather than copying the injection molded hollow design. Hack it better in OpenSCAD
Be sure to run the ABS hot ~255C and at a high enough % to get the layers to stick properly, I also soaked in acetone to strengthen the layers.
