Stock handle became cracked, so I've replaced it. Original inner handle bar was OK, as it is made of PA-CF.
Handle is designed to be printed vertically. No supports needed for the upper end, but some are for openings.
Clamp needs supports.
I've printed them with PETG.
UPD: you may need to file down a clamp, if it prevents puck from falling out. Like I did…
