These holders make it easy to store your AXA size quick change tooling in whatever form you likeI have used both PLA and ABS to make the toolholders, though the ABS tends to curl more. You will have to increase the size by 10x when importing into Makerware, as I drew the part in Inventor using inch scale. I printed these standing upright as in use, so there was no need for support or raft.
