A simple storage solution for my heat insert tools. Nothing fancy. Sizes M2, M2.5, M3, M4, M5, M6, M8.
Depending on your brand/style of insert tools, this may not have the correct hole sizes for your bits.
I can design a remix for you with different dimensions if you'd like.

Please post a picture/make/comment if you use this design. I love seeing my designs helping other people out.
