Oarlock Liner

This oarlock liner was designed to replace liners in an oarlock listed for 1/2 inch diameter oar shafts. It was purchased from Amazon and listed as "Marinebaby 2Pcs Boat 316 Stainless Steel Oarlock Socket Side Mount Rowlock Socket for 1/2" Shank", which are very nice oarlocks. The original liner lasted a year of moderate use, but eventually the top rings wore out.

The OD of the liner measures 11/16 inch, but it will likely fit in a 3/4 inch diameter oarlock. The overall length is 1.5 inches.

I printed it with PLA on a SeeMeCNC Rostock 3.2 at 40 mm/s. I used Cura 4.4 to slice at 0.2 mm layer, 100% infill, with a 3 mm skirt. Print time 28 minutes.

Works well so far.
