Yes, pickguard material is usually PVC which creates a hydrochloric acid vapor when you laser cut it. What you can do is get an mdf template laser cut and then using it with a table router/follow bearing bit.
3D printing is not that difficult, but Jim is right regarding the texture - however, it can be very easily filled and smoothed and if you are using PLA then Rustoleum actually bonds to the plastic and is very high wearing. I've done a few bits and pieces with my printer. I can do the required drawing/printing, but I would need really good measurements to work from.
Happy to have a go if you can supply some details.
