Gridfinity ISO30 Collet Chuck Tool Holder

This is an ISO30 Toolholder that fits 4 ISO30 collet chucks. It uses a 2x5 gridfinity pattern to achieve this, but in reality it is a 4x5 because of the overhang of the pullstud and any installed tools.

BT30 toolholders will also fit into this model! BT30 and ISO30 are oftentimes interchangeable. But for tool storage, you can use ISO30 storage for BT30 because BT30 diameter is 46mm and ISO30 has a 50mm. It wont give you the glove like fit you get for an ISO30 toolholder, but it works, and I have found this angle better than most other models online for properly balancing the tool. 

I have printed these in PETG, PLA, and ASA without problems.
