Printed in PETG on its side with no supports, 15% infill (prusaslicer defaults).
It seems very sturdy, very well designed and prints very easily. This cleat is every bit as good as what I would expect from a store bought dock cleat.
If I were buying screws for this dock cleat, I would get size #10 with rounded heads (the ones pictured are smaller unknown size 1 ½" screws). About 20mm (¾") of the length of the screw will be in the cleat itself, so if you want 1" of screw to mount it, use 1 ¾" screws.
I removed the logos because a logo really ruins something like this for me.
The author remixed this model.
