Thought I'd share my tiller tamer. Could use a few tweaks but I thought it came out pretty well for a first attempt.
We bought a kit that my son assembled for about $300. He is currently using a soft material to make cellphone cases. We normally use PVC whichThats really nice. I guess 3d printer material has improved over the years. I thought the plastic "inks" were very brittle. What is the material? What printer are you using?
Most start with PLA then move to ABS for longevity and heat resistance. The printers are farely cheap. I got mine for around $300. The 3d cad programs can get very expensive. A typical 2 pound spool of filament will run from $20 to $40. Perfect for one off projects. My son has built several drone bodies with ours.Thats really nice.

You can get Autodesk (full version) for free as a student for two years. To buy it costs a couple thousand dollars.Printer filaments have improved in that there are more options. Nylon is great for durability but not all printers can handle the higher temperatures required. I've read that PETG is also a big improvement but I haven't tried it yet. I went with old school PLA for this project because it didn't seem to me like a high stress application. I tweaked the clamping force on the line so that it will slip long before the tamer breaks.
The printer I'm using is kind of home brewed. I started with budget kit built printer called a Tantalus. When I got the itch to upgrade, I just took ideas that I liked from other printers and designed my own.
I'd be happy to print one for anyone. I'll go ahead and upload it to thingiverse.com tonight.
If you're looking for a cheep CAD program, Onshape.com has a really nice one that runs in your browser and is free for hobby use. I used Autodesk Fusion for a while (big player in the market) and ended up switching to Onshape.
