This grip fits on the end of a bike or scooter's handlebars.
This was made to be printed in a flexible filament material. I don't think you'll be able to fit it on the handlebars if you use a non-flexible filament. I used SainSmart Flexible Black TPU filament and they came out great.
They were printed on an unheated glass bed at 225C, with a 25% fill, and 2 loops. I slowed the printing down to about 20% slower than the speed I print in PLA.
