Sekskantet stempel venstre

The hexagonal shape locks in perfectly and feels sturdier than the original piece I lost. Clicked right into place on the left side, took me under a minute to swap it out.

My old left piston was so worn it kept slipping, and this hexagonal one clicks right back into place like it’s brand new. The fit is snug and solid, exactly the left-side shape I needed to get the device working again.

Finally found the exact replacement I needed—the hexagonal shape fits perfectly into the left slot, so no more wobbling during use. It’s machined precisely like the original, and the swap took me under a minute. Glad I can keep the device going instead of buying a whole new setup.
