Hope Pro 4 Seal Installation Tool

thingiverse

This is an installation tool for Hope Pro 4 rear rubs (emulates the HOPE HTT1003-06 PRO 4 Seal Tool). I converted my old mountain bike from quick release axles to thru-bolt axles and purchased new hubs, along with the conversion caps. Unfortunately if you pull the cassette holder out of the Hope Pro 4 hubs, you need a special tool (basically the correct size piece of pipe) to push the seal back in. Rather than spending $30+ dollars and waiting a week to get a tool that I'll use once, I made some measurement and 3D printed my own. I tested it and it works perfectly. I would suggest printing it with 4 outer layers to get a lot of vertical strength, as you need to hammer on it. I hope this helps a few other people out there that ran into this poorly documented problem.
