CAT40 Toolholder Label

When using CNC, the quality of your tool holder is critical to the accuracy and finish of your part. It is important to measure and characterize the relative quality of your parts. Runout and balance are the two most important aspects of your holder. But most people track tools, not holders.

I track holders, instead. In a spreadsheet, I keep the quality characteristics of my holders as well as which tool they are holding.

But to keep physical track, I made this holder which I 3D print with the data I have collected.

The data from the spreadsheet is entered into the configuration table in my [OnShape model](https://cad.onshape.com/documents/74009be420f585f1eb09fb7f/w/8f68320e909439ce1169777c/e/3081d42f578f94fa0db20887?configuration=List_IXNCUTXJXP1it0%3DDefault&renderMode=0&rightPanel=configPanel&uiState=6574ea6c33347e39fc373e6d), allowing me to easily print these holders as needed.
