Printed in abs 20% fill 235C. I used my filament fan when printing out this collars part. White tube measures 1/4 inch and black tube measures 7/32 inch . Used a 9/32 inch drill bit to drill out the caps for the white tube and use a 1/4 inch drill bit to drill out the caps for the black.
5/13/2014 When printing cap with grips print out one cap at a time. Settings on printer where infill 20% extrude temp 230C, Bed temp 110C and turn in filament fan if your machine has one. Makes grips turn out nice and clean.
