Another version using scaled multi-transform.

Thanks for all the help, I think I am getting the hang of it a little bit.
My little project is now (hopefully) 99% complete. Next step is to convert it to something that can be 3D printed.

This is the result so far is anyone is curious :D

Looks nice :D

Regarding the model, only had a cursory look, but I think you could've hugely reduced the number of constraints if you had made better use of geometric (the prefered kind) constraints, equality mainly. 330 constraints probably could be 100?

Maybe make a thickness to reduce plastic?

Looks good. Just a few remarks:

Should use PartDesign fillet instead of Part fillet. If you are going to use Part fillet you should make a clone of the body object in Draft workbench, then apply the fillets to the clone (hiding the original body). This prevents out of link errors/warnings.

Sketch should be inside the Body object, not outside.

There are self-intersections as determined by Part -> Check Geometry tool (with Bopcheck enabled). Not sure if that is related to using Part fillet, probably not.

You plan to mount this on a wall? If so, by what means? Perhaps some mounting holes could be added.

Looks good, great progress.

Now just select File>Export and choose stl...probably. 8-)

Thanks for the all feedback! I will look into that.
Obviously I have a great deal to learn, but I was very with the amount I have been able to do in a short time.
@TheMarkster: it is going into a toolbox (lying flat). I might add some pockets to recess some magnets in, so it won't move around.

@Bance, I will read up upon the constraints, but there is some variance in hole diameters for the different screwdrivers, so maybe that explains the high number of constraints? But I'll agree, it probably could be modelled a bit more elegant :-)

To duplicate many of something you can create one complete solid and then array the pocket feature.
Also notice how sketching the radius saves placing a fillet. When the outer edge of the block is selected then the entire block edge is filleted in one shot.

My take on better constraining. Made just the first two slots as example. Proper tangencies, using a Point with "point on line" and vertical constraints to give offset of the arc.

@kisolre,
Thanks, seeing that, that makes sense. I didn't see how to do that, so worked around it with a sort of box construction.
Did you add the bottom point to the existing arc, or did you draw the arc in a different way?
