 # Autoprop
 
-Bearing caps for the autoprop
\ No newline at end of file
+Bearing caps for the autoprop.
+
+These are replacement caps for my APS H5 autoprops, but they will probably fit some other models as well.
+
+I once lost a blade, and together with the blade the bearing cap. It was bad enough I had to order new blades, and I didn't want to order a new bearing cap as well.
+
+The advantages of my design:
+
+- The bearing caps are much lighter than the metal ones. This increases the service life of the bearings and saildrive.
+- A special tool is no longer needed, a regular socket or spanner #32 will fit on them.
+- No more tool holes that get clogged up with marine growth.
+- Less metal, so less consumption of the expensive annodes.
+- You can just print new ones if they get damaged or lost.
+- You could print each cap with a different color so it is easier to identify the individual blades.
+
+The standard O-rings and grease plugs will fit on these caps.
+
+## Notes
+
+- I used PETG for printing them, as PETG is oil and water resistant.
+- My sure to dry the filament properly or it will cause leaks.
+- Due to the design, use of a support interface layer filament is necessary.
