Looking good :)

Hopefully I can get some more time with my own copy of F360 soon!
Thanks!

It’s a really great application. I’ve been designing simple stuff with it for a few years, with a break while my 3D printer was out of order (it still is, but I bought another one :)).
It really is good, and for free if you aren't a business, it really plugs into the maker world. My 3d printer isn't the best and needs a little TLC. First though I need to try and clean up all the stuff around it!!

How are you going to do the key labels? Do you have a laser engraver?
I don't know if I will, to be honest. My plan was just to leave them blank to be able to print spare keys if I need them. A laser engraver would probably not be the best to use on 3d printed plastic. :)

I have done this recently to make a CRT monitor - I have been making a thing to fit in a Mac SE/30 case. It's the reverse of the curvature, concave, but same thing.

Start with your block of material and define a curve that is the correct curvature across one axis. This would be a side-on view of the key where you are drawing a new sketch with a curve that dips down toward the key. It does not matter at this point the distance from the curve to the key, only that the curve is correct. You can parameterise the distance from the centre of the the curve to make adjustments easier later. Once that curve is done finish that sketch.

Next you make a construction plane that is perpendicular to that curve. You should see the plane appear with the line of the curve going through the middle of it.

On the new construction plane you will make a tool. Start by making a rectangle that will be wider than the side of the key. Then bisect that rectangle with another curve, where that curve dips down to the centre of the key just like the first curve. The rectangle is divided by the curve.

Next you sweep the convex portion of the rectangle as a tool over the key along the path that you defined first... that cuts away a spherical cut! Move it up or down to control the depth of the cut.
Oh, like an ice cream scoop? Thanks for the guide, but I think I managed to find a radius for the lofting that is quite close to the original, so I think I'm going with that for now.

Yeah, well... My broken Prusa clone is buried under lots of stuff in the garage, so I bought a cheap PrimaCreator P120 v4. I think I just bought an original Prusa i3 from a friend tonight as well. But that needs some work :)
A kludge is a workaround or quick-and-dirty solution that is clumsy, inelegant, inefficient, difficult to extend and hard to maintain.

From the results you posted it looks like you have the perfect spherical cut going on for those keys already but I was pleased to find out the path sweeping approach so I thought I would share it.

Yeah, I can understand that. It sounded awesome! :D

I will have to try it sometime, I will need some ABS, laser masking tape and color fill, I would think it would work OK as long as the surface is smooth.
Too much going on right now to mess with the laser and I need a good venting setup for working with plastic as the fumes can be really bad for you.

If it's worth doing, it's worth overdoing :D
