I was unable to find some elements for another ropewalk posted here so I made this one it uses 608Z skateboard bearings so they are easy to get nearly anyplace.
Here is the file in Zip if you cant open it let me know Ill open and post separate STL files along with the instructions for assembly. Here are pictures of the one I printed minus the shuttle that's still being printed.

Thanks that looks awesome. How long was the print cycle?
Have you found a rope server hole anywhere?

it took a total of 8 hours to print, but I had quality turned up almost to max so I got a good clean print. I printed gears for a server, but haven't had time to go to Home depot to get the wood to assemble a server yet maybe tomorrow. When I'm done that build Ill post it here in this forum section along with measurements, Parts list and a how to assemble. other then the gears its gonna be fairly easy. Later on I'll adapt both to use a motor and will post that as well, but for now at least folks can get a working ropewalk with ordinary parts you can find easily. if you look at the prints you will see a dull side that's the side that's down on the heatbed and the first layer I hate that it leaves it dull looking, but that how they all leave parts with a heated bed I can gloss it up using acetone, but I'm going for function over looks in this case.

I've never played with 3d and was astounded when your files popped open in a viewer right away under Windows 10! Now that I see the pieces individually
it's a lot easier for my mind to grasp the ropewalk's function. Your design takes into account everything from extra material support around the screw holes to wall re-enforcing....brilliant engineering mind! Thank you for the design. I *know* it will come in very useful

Damn, the front part was too big for my printer :confused: but apart from that a great design...
you can scale it all down Brother, but in doing so you will have to refigure the bearing size. The good is bearings come in just about every size one could think of. The bad is finding that bearing. You could use brass or bronze rod as a bearing however.

The idea is just to keep the plastic from rubbing plastic a nicely polished brass or even aluminum bushing will be just as good if you want more security on wear you can make the hooks small enough in diameter in the area they are in the bearing and use a small brass band glued to it so you have polished brass against polished brass for wear and at that point you could use a tiny drop of lube. wood bushings would also work even if the plastic was directly against it. My print bed is 8x8x8

Easy conversion to power the ropewalk. Everyone a drill so I thought just buy a longer bolt turn it around in the assembly and stick it into a drill. It would be best to remove the crank handle and its bearing. I plan on making long sections of rope so I don't have to do it so often that will require some help to do and My Wife is always happy to help me out so the easy way to convert this thing was simply a Drill.

I also stopped in to home depot and picked up some Oak board for the Server unit. It will be powered the same way. I am waiting on some Aluminum Round stock and I can turn it on the lathe for the server so when I get that Ill assemble this thing and post the gear files and assembly. You wont need a lathe for this if you have a Drill press I'll show how to turn the rod with a press very easily. The Rod will have a hole through the center to pass the line through it will replace two of the bolts shown in the picture they are only there for testing the assembly for gear mesh.
