Howa bolts can be stripped without tools. This is pretty handy for cleaning but is essential when you get a blanked primer (sadly something that Howas seem a bit prone to) with bits of brass blown through the firing pin hole. If you don't clean them out then they can cause light strikes and failures to fire. Although the bolt can be disasembled by hand, it takes a very firm grip and can be challenging if it's cold and wet. So I made a simple tool to help. It's now trivial to get the bolt apart, and it's also pretty easy to cock and uncock it (which is impossible by hand - for me at least).
My first print of this wasn't strong enough. The second attempt, with extra walls and 50% infill, was fine. I printed in ABS but I guess that PLA would be fine.
