So my advice would be that if you cant find what you are looking for in 15 minutes on these websites – it is sometimes just as quick – to get out a digital vernier – and pop down to the workshop – and take the respective dimensions – and model it up yourself – and at least you know if you have done the job properly – then you can rely on the geometry you have modelled.
You could approach KIMLA directly and ask them for a 3D model – and explain that you want it so that you can determine/visualize whether the part you want routing can be machined or not from a 3D space perspective (which is why I assume you want the 3D model of this part). You might if you are lucky get a 3D surface model – assuming your company owns a KIMLA router.
Another approach (which I wouldn’t use for this example) – is to 3D scan the part – and Faro do 3D scanners – from which you can get a 3D model generated – but it is expensive option.
The availability of 3D models keeps improving every year – but we are a long way away from getting every 3D model we might want. However, you also need to think about things from the perspective of the original equipment manufacturer (OEM)- since if everything was available in 3D – then there would be a lot more copying of equipment going on – which is something I have seen from my former company’s perspective.
Hope this is of some help.
