I have searched and searched and I can't find anything on the forums - there are probably many posts about this, but I simply can't find it anywhere. I only found a post with a barrel of 43mm's showing 67mm. But knowing Tina, there is probably some difference between the 43 and 39mm chips. 
I have a set of 39mm web molds coming my way very very soon and I want to 3D print some racks for these. So I need to know the height of a barrel and I don't own a barrel. Can anyone with a pair of metric calipers tell me the height of a barrel of web mold hybrids?
Thanks
