CC Inline tool

This tool is to remove the inner air can on a CC Inline rear shock. It test fitted perfectly but I have no idea if this is strong enough to do the job, not doing an air can service for another 6 months. Total 3d noob here so unsure of what % of infill you should do, guessing at least 70% to keep good strength. Was not sure if this would be strong enough so I drew up another called Beefy, it's twice as thick. I have not printed it out yet so it could be scaled wrong.
