Yeah… I made them in onshape. I can share that. The actual STLs won’t be that helpful because they are for the erratic hole I made in my counter.
Onshape is free for non commercial use, but they don’t make it obvious when you try to sign up. Let me go grab the link.
It’s definitely a bit of a mess in there. Sorry about that. But if you need any help, ask. And please post more details about your project in a new thread so we can all live through it with you 
. The table I have is not waterproof enough for a coffee bar, but hopefully you have a plan to fix that.
