Description
This is the first thing I've designed. It's a strain relief upgrade for my Makerbot Replicator I made using Autodesk 123D Beta.
The Replicator shipped with a fairly fragile method of tethering the main wire to the extruder carriage and I found that I would have to frequently reattach it (it was a zip tie pulled over a screw head).
Fed up with this design I made a clip which is held in place by the same screw which held the zip tie in place. I took special care to ensure that the screw remains in the same place as it did with the old strain relief solution.
As soon as I get the chance I'm going to be adding a small channel to let the wires come out of the clip at the bottom so that it isn't pinching them as much when it's all screwed together.

Instructions
Print out the piece, cut the zip tie holding the wire bundle to the carriage and remove the plastic shim on the screw.
Remove the screw from the assembly and carefully push the wire through the clip. I intentionally made the clearance small so it doesn't pop out during operation.
Put the screw through the eyelet and screw it back into the carriage.
Marvel at how secure it all feels :)
I printed mine using 0.3mm layer height, 0% infill and 2 extra shells for rigidity.

I was surprised how quickly the tube frayed under so few prints. This definally helps keep things tidy. Thanks.

Ours is going strong! We had to cut the zip tie to replace a thermocouple about a month ago and used this replacement bit instead of another zip tie. Works fabulously!

This is just what I needed. I had to remove the original zip tie and I could never get a replacement zip tie to hold. Thanks!

This looks like a great upgrade.
The small channel you mention adding... do you mean a cut up under the backside of the curved portion so the wires can exit that way?
My intent was to cut away part of the bottom of the hook to let the wires exit without either being pinched or forced to come out the side. I know I've promised it but I've been too busy with work to finish off the model.
