Won’t be perfect haha, they probably won’t feel as smooth as the actual RSMs since there’s no way to perfectly center the spacer. ---

I went a different route and threw some modified PGM posts on the ultra lights. ![IMG_7793](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/a/e/2/ae2460996b815eaf0430484af79639f686ff9e5c.jpeg) ![IMG_7794](https://us1.discourse-cdn.com/flex015/uploads/yoyoexpert1/original/4X/e/b/0/eb00e6a48da1bdb2a2fd1f3f21125c84284f3b83.jpeg) Edit: I think this is a good solution to the issue with centering the spacer too @yoyospirit - Not really much vibe. ---

> [@Applepooh](#): > > Quick n dirty write up? - Cut down the bottom of the PGM posts so they’re flat (I’ll probably cut them down even more so the posts are shorter). - Drill through the top of the ultra lights so an axle will fit through. - Screw the post and ultra lights together with short axle and add the necessary parts. ---

Nah it’s fine, USPS probably thought it was flat and tried to send it through the “flat” machine. That happened to @irdaprez and me once with side effects as well. At least you sent it in a padded envelope so it survived! I used a plain envelope which was not a good idea… he ended up with an empty envelope as the purple SEs squirted out the side probably thanks to the rollers on the machine. ☹ ---
