Printed in PETG on Prusa Mini+ with 0.2 layer, 4 perimeters and 20% infill. There's Atera logo on one side, which might not print great in PETG. Print piece 1 and 2 separately. Glue a piece of 2 mm rubber that fits in the curved part to protect your bikes from damage.
Photo of the final assembly will be added later.
