seitech dolly axel spacer
This spacer fits a 1" axel that are used on many dollys. This one was made for a seitech dolly for a sunfish sailboat, to take up the gap when using these wheels on Amazon to replace the originals. https://www.amazon.com/dp/B08K2N43X9?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1
I printed with PETG, using 15% 3-d honeycomb infill.
