Knock Out Tool

Originally designed for vintage pen renovation, knocking out the nibs without damaging them, this block can also be used for removing broken centres of bearings from your prints. The block will currently fit a 69-70mm diameter tube, resize as necessary. Just print a shaft of an appropriate size and use something to knock it through whatever is stuck. I like to use a THWACK hammer.Boost MeHi all. Boosts are always appreciated as i know they are hard earned.
