Park pro repair stand replacement lock blocks

thingiverse

I've got a bit of a niche item here, probably not very useful for anyone, but I'm curious to see just how far I can push 3D printed parts. I've lost one Park Tools pro repair stand and can't find the lock block set. I could order a replacement, but I want to see if I can make do with what I have. I drew up these designs in Fusion 360 and printed them out. If you've got a Park stand that these will work on, you probably already have the lock blocks, and since they're milled out of steel, they won't wear out anytime soon. These need to be printed solid, and it's designed for a big M12x1.5 bolt I had left over from suspension work on my car, but it actually works. As I tightened it down enough for it to hold a bike, it made some unhappy cracking sounds, but so far it's held up just fine through several repair jobs. At the moment, I have it set just tight enough to hold a pretty big bike (my Fuel EX in an XL 21.5" size holds just fine), but I can push on it to reposition. The Fusion 360 export file is included if you happen to have a bolt that'll work and isn't an M12x1.5 thread.
