3D model description

Hook tool for gathering shift and brake housings when dealing with Trek's Control Freak internal cable routing. Very likely useful on other brands' internal routing as well. Push all the housing and hoses to one side, reach in through the ziptie access hole with this tool, then get the housing and hoses into the hook. Once they're in the hook, push the ziptie into the slot in the handle where it will route around the housing/hoses, and come out the end of the hook. You can then pull the ziptie through, remove this tool, and cinch everything down.

Based on a 3D printed design from Trek's own service folks - thanks to David of Trek Bikes in Chattanooga for sharing photos and dimensions of the Trek version, which broke when he was using it. This version will hopefully prove to address the issues he found with the original Trek design.

NOTE: Tagged as a work in progress as I'm waiting to hear back from David to see if it works as well as the original. Files will likely change based on his feedback. Appears to work for me but I'm not a full time pro bike mechanic so don't have as much direct exposure.

Note: I wanted to try Cults3D as a possible alternative to Thingiverse, but after giving it a bit of a look, I'm not super impressed. Feel free to visit my Thingiverse page if they can manage to keep that site running:

I went to school as a mechanical engineer, and got interested in 3D modeling, specifically the SDRC I-DEAS CAD/CAM software system. This interest got me my first job working for a CAD/CAM reseller doing pre and post-sales support. I was lucky to be involved in 3D printing in the early 90s - for a demo of rapid prototyping, I modeled the mouse from my HP-UX CAD workstation and it was rendered via stereolithography. I still have that model, but across the years I stopped using CAD and moved to systems administration. Now that 3D printing is affordable and mostly reliable, I've gotten into it and am having a blast. I printed all the usual cute little trinkets and tchotchkes, but quickly got bored of that. What I find most interesting is needing something, then spending a little bit of time in a CAD program and soon after that having a real, functional version of the part in my hand.

I'm a cyclist and bike mechanic as a hobby and a side job, and have found endless applications of 3D printing to both bikes and bike maintenance. Coworkers have also come to me with many varied requests, each of which has been an interesting challenge and an opportunity to learn.

I am constantly learning, constantly trying to challenge myself to learn new things and technologies, so hopefully as I progress my designs will continue to improve.
