Park TS-1 truing stand radial hop indicator

thingiverse

I love my TS1 truing stand - have been using it since the early 90s and have built and trued countless wheels with it. One thing that bothers me is relying on indicators to visualize a radial hop; if the wheel has any lateral hop it can be difficult to see the radial hop against the curved top of the indicators. To solve this, I've previously taped a straight edge to the indicators, but that's frustrating. I created this extremely simple thing to just drop on top of the indicators and provide a nice level reference for spotting radial hops that isn't affected by lateral hops. Print it in black if working with a black rim and it'll make any lateral runout very noticeable. It's incredibly straightforward, but if you see potential for improvement, let me know - or I've attached the original Fusion360 file so you can edit it directly. Just post a remix if you do, I'd love to see it! **Update:** Sep 1 2018: * I was printing another one to use at work, and realized why my first version had a longer bit. I cancelled it while the sides were even, and it works perfectly fine without it. I modified the model so it's smaller and prints faster, and still functions flawlessly.
