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, purchasing new hubs and conversion caps in the process. However, if you pull the cassette holder out of the Hope Pro 4 hubs, you will need a special tool - essentially a pipe of the correct size - to push the seal back into place. Rather than spending $30+ dollars and waiting a week for a tool that I would only use once, I took measurements and 3D printed my own. After testing it, I can confidently say that it works perfectly. To ensure maximum vertical strength, I recommend printing it with four outer layers, as you will need to hammer on it during the installation process.
