E2 oiler boxes on your linear blocks, Your maintenance is now once every???. 20$ per block for a total of just over 200$. (For off brand on amazon unsure what the hiwin ones are but they dont fit because C3D linear blocks have the oiler port slightly higher (can trim the hiwin ones to fit and increase contact area minorly.)
Advantages:
-Takes as long as one maintenance to install.
-Boxes are hot swappable press fit with an O ring on the fitting to prevent egress.
Disadvantages:
-monei (but if you bought that SMW vise/fixture plate I know you can justify these puppies)
-Unsure if the Y axis can support them without losing travel (have not checked but x and Z are good you just face them upwards on the Z axis and inwards on the x axis probably the same on Y)
-Have to modify the oiler box oil applicator so that it fits as well as drill new holes so the original Wiper can go in the middle of the sandwhich
