This is a remix from the mighty thing : https://www.thingiverse.com/thing:545345 aka the exact same one you can get on eskating https://eskating.eu/product/htd-5m-36-38-40-42-teeth-nylon-carbon-abec-11-genuine-flywheel-refly-wheel-pulley/I fact i have the eskating one, the irl pin to pin distance is 40.3mm, this is a very tight fit make sure your printer is well calibrated, if not, you may have to resize X and Y of the part before printing. (i had to print mines at 99.75% for exemple)Then, all you have to do is print your own jig, sized to fit your own sprockets so you can center/drill/countersink corresponding holes in it. Bolt everything a little at the time with m5 - 70 to 80mm screws. Here's how it look on my board :https://www.e-sk8.fr/t/build-sur-loaded-vanguard-simple-et-a-lancienne/11027Printed thoses in PLA for testing pruposes, i think it may be to brittle. Would recommend to use a more durable filament like ABS/PETG/Nylon and such as well as nicely torqued screws to really compress everything.
