That looks good. I checked the hole and cutaway positions and they are correct. The width and length seem to be a bit less visually than I'd expect. I'm not sure the fins should go sideways. I guess that would depend on how someone plans to install them. That seems like a lot of machining. Is it easier to cutaway the connector area rather than drill some countersunk holes?
Sorry I missed the dimensions but it is 80x90x35 mm
The plan is to make it from 165x35 profile , that is sold in 1m long bars
I can now confirm the final price it's 3.92 Eur ( I missed to add the VAT price from the supplier)
The connector area is cut away . On the projected view you see the radius on the inner edge, that is needed to avoid additional side operation on CNC mill
Do you want me send cad data to be added to github ?
