I wanted to make a low profile wheels for the SAMLA storage box so that the entire box, including the lid, would fit under the NEIDEN bed, also made by IKEA. The bed clearance height is only 20 cm.
I used a steel rod with a diameter of 4 mm x 125 mm to connect the roller to the body.
Silicone tubing of the appropriate diameter is to secure the rod at both ends.
Material: PLA, 15% infill, I recommend print body with rim. Right side body was just mirrored in slicer.
