I always forget when I need to do certain chores that need to be done quarterly. i.e. oil the deck, fertilise the lawn, etc.
I've put a few of these up in the garage that I can see at a glance what needs to be done, and when.
The two arrows show when the chore was done last and when it's due to be done next. I've modelled for 1, 2 & 3 months. I might add others at a later date.
The label recess is designed for my Brother P-Touch labels at 13x50mm.
I used the Fusion 360 thread profile generator to create the threads. When printing the nut, I needed to scale the X & Y direction to be 103% to get a smooth operation. Maybe that is just my printer. DO NOT scale the Z axis direction or you will change the pitch of the threads and the nut still might not go on.
Scale the nut to 103% along X &Y if necessary
