This will help you with that.
Another thing I consider is you to CAD absolutely EVERYTHING. It might sound like a pain, but it saves you from having to eyeball everything, which means you have a very small chance of messing anything up. Onshape is a very good software for this, as you can pretty much run it on any computer newer than 2017 with no problem, (i have a 2015 macbook pro and it is a bit choppy, but it does the job) and it has a library of almost all of the vex v5 parts in existence.
