I needed a bigger headset spacer after I got a different stem for my bike, and I was too lazy to get one, so I designed this one. It's made for a 1 1/8" steerer tube, with a height of 20 mm (let me know in the comments if you need a different height or diameter), and an aesthetic spiral pattern around the outside. It's worked perfectly over the past 3 months, although I wouldn't be surprised if it's loosened up over time, and thus I'd recommend re-tightening your stem every once in a while, and replacing it around once a year. It Printed in PETG, with as many walls as possible, concentric top and bottom surface texture, and arachne wall generation.
