Spinlock Tiller Extension Bracket

The tiller bracket that comes with Spinlock tiller extensions does not seem to have any business on a race boat. UV gets to it, it breaks when anything snags on it, doesn't hold the extension very well in the first place. $15/shipped to replace it.

Here's a take at a better/cheaper one. Note that the two center holes line up with the stock holes. I added a couple more (in case you want to use smaller screws and more of them).

Print with PETG for better UV resistance (or just PLA if you cover your tiller when not in use).

For me this was great:

1.6mm wall thickness
50% infill
Print on profile end, no supports needed for me.
