I designed this to attach a dolly to my bike, similar to the Burley Travoy. My dolly design did not work out and was very unstable, but this hardware works very well. You need to measure your seat post diameter very carefully, with callipers. +/- 0.5mm can significantly reduce the effectiveness of the seatpost clamp. within 0.2mm should be fine I think. seatpost angle can sometimes be found on the manufacturer's website. it's not suuuper important to get it accurate, the bolt just won't be perfectly vertical. depending on your application this is probably fine. Providing 3MF files so that my print settings are also saved. I printed with brim and tree supports in Cura. Worked flawlessly with PLA. These settings should be saved in the 3MF file, but I'm new to the file format so please let me know if it didn't work feel free to provide feedback
