I loved seeing Rope Series that JamesThePrinter has been making and it inspired me to figure out to create my own version.
Originally I explored parametric modeling, but I quickly ran into a plethora issues so I switched to Blender Geometry Nodes. (btw…they are amazing). After a lot of YouTube tutorials and weeks of messing around, I've got a version 1.0 of the Rope Wrap Node.
You simply an import a model—or create your own shape—into blender and with a couple clicks have a beautiful rope wrapped around the object. Export as an STL and print!
I'd love to see what you all make with this!

.Blend file is optimized for creating 3D printable models
- Unit length & scale is set to mm
- Viewfinder grid & focal length set to correct scale

Current Limitations
- Top and bottom of object shape must be a perfect circle
- This is a limitation due using a spiral curve to fill in the caps. In theory, I might be able to use a “Raycast” node to fix this, but I haven't figured that out yet
- Set/Apply object scale to 1.000 before connecting geometry node
- Not doing this will cause the top & bottom of the model to scale incorrectly. I'm not sure how to fix this. Regardless, it is just a good blender practice to always reset your scale to 1.000 before applying any modifiers.

- Scaling in “Edit Mode” may causes issues with top & bottom geometry.
- It seems like this might be based on the Transform Pivot point? I can't get this to replicate reliably.

TODO
- Top & Bottom spirals work with non-circle based bottoms (see current limitation 1)
- Similar to Rope Tray by @JamesThePrinter
