+# case-project TODO list
+
+### Actual TODO
+
+- Finish refactoring files to use the application style, like in `yBar.scad` 
+- Implement better build script using python
+
+### Ideas
+
+- Instead of using names like 'mainRailSlotToInnerYZFace', experiment with a central distance/dimension directory. Like:
+```openscad
+// Define identifiers:
+mainRailSlot = "mainRailSlotIdentifier";
+yBarInnerYZ = "yBarInnerYZFaceIdentifier";
+
+// Define distance
+setDx(mainRailSlot, yBarInnerYZ, 3);
+
+// Define dimensions
+setX(mainRailSlot, 10);
+setX(yBarInnerYZ, 0);
+
+// Then, you can get distances like:
+dx(mainRailSlot, yBarInnerYZ); // == 3
+dx(yBarInnerYZ, mainRailSlot); // == 3
+
+dx(mainRailSlot, blah); //throw error
+
+// And you could possible chain distances like:
+
+dx(yBarInnerYZ, mainRailSlot, sideConnectorSlot); 
+// which would eval to:
+// dx(yBarInnerYZ, mainRailSlot) + x(mainRailSlot) + dx(mainRailSlot, sideConnectorSlot); 
+// OR 
+dx(yBarInnerYZ, mainRailSlot, sideConnectorSlot, includeFirst=true, includeLast=true);
+// which would eval to:
+// x(yBarInnerYZ) + dx(yBarInnerYZ, mainRailSlot, sideConnectorSlot) + x(sideConnectorSlot);
+```
