I found that none of my bigger bikes fit on my new TACX T3050 work stand. This adapter fits my XL frame full suspension fat bike with room to spare, so it likely fits your bike too! The end is tapered so you can press fit the extension in and it stays in unless you intentionally pull it out. If you keep your work stand in a place where a material more heat resistant than PLA would help, don't forget your brim/enclosure. Mine was printed in PETG with >20% infill. If you print it on its side with supports, the part will likely be stronger.
