Working out GREAT! I printed a second one with slightly smaller bore (from 2.8mm to 2.5mm) and it suits the bowl, baccy and me just right. No taste from the stem, and comfortable in the mouth. Shorter stem is definitely more comfy and easy. Tenon fit is secure. I have no hesitation doing more of these for straight stems at least (i believe will get smoothest inside bore that way) but may try some slight bents someday.Curious how your stem is working out.
