What a fun thread ! Great work everyone.
For me it would probably be my boat floor I am obsessed with upgrades and doing things myself. It was the actual reason to build my first Cnc the mpcnc. But I found I needed bigger and well it ended up working alright.
Now I have upgraded my table and am on the lr4 so I should have more flat consistency.
Sold my beginner boat to my neighbor and boat a project boat at the year end from way up north.
It was a great project to learn multiple tool paths. How to digitize an area. And some gel coat learning too.
It’s some cheap Eva foam from Amazon. It’s lasted great so far.
