I found this neat little piece of hardware on BangGood.com
Do you think it will fit our K40 stock tubes?

60-90mm I think most 40W tube are 50mm you will need a way to center it.

Here’s one that claims 50 to 80mm: http://www.aliexpress.com/item/Laser-tube-support-Mount-Barackets-for-50mm-to-80mm-High-quality-diameter-adjusted-for-laser-machine/32333373974.html?ws_ab_test=searchweb201556_1,searchweb201644_5_79_78_77_82_80_62_81,searchweb201560_1,searchweb1451318400_6149

Although it shouldn’t be too hard to 3D print one

I’ve already tried that, the base is too big to fit in the k40
