Park pro repair stand replacement lock blocks

prusaprinters

<p>This is a bit of a niche item that probably won't be terribly useful to anyone.. I've got two Park Tools pro repair stands, and can't find one of the lock block sets. I could order up a replacement, but I'm always curious to see just how far I can push 3D printed parts, so I drew these up in Fusion 360 and printed them. If you've got a Park stand that these will work with, you've probably got the lock blocks already, and since they're milled out of a block of steel, it's not like they're ever going to wear out.</p> <p>They need to be printed solid, and it's sized for a big M12x1.5 bolt I had left over from suspension work on my car, but it does actually work. As I tightened it down enough for it to hold a bike, it made some unhappy cracking sounds, but so far it's held 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.</p> <p>Fusion 360 export file is included in case you happen to have a bolt that'll work that isn't an M12x1.5 thread.</p> <h3>Print instructions</h3><h3>Category: Sport &amp; Outdoors Summary</h3> <p>This is a bit of a niche item that probably won't be terribly useful to anyone..

PLA<em>might</em> work well enough, but I didn't try.</p>
