Hi all Thanks for your answers. A plan needs to be detailed. For the 3D model for sure details are not needed, but for the woodworker he needs detailed plan.I'll just do the model with a stud.

I have tried to drew the fittings myself.But am just a beginner in sketchup and was wondering whether the fittings existed that could save me some time. They are for use with small shelves that will be "clipped" together to make a bigger furniture.
As soon as I draw the model, I will post the idea

Here the ball latch type

Hi,

I am looking for these two models in the warehouse and can't find anything that is alike.

Does anyone have a "double ended christmas tree fastener" and "ball latch fastener" model?
