About this 3D model

Simple, made with Design Spark Mechanical. My daughter was like, where are the taps!@#! she wasn't impressed at all, so I added some taps as a separate file and melted them on with a lighter, now she's happy :) Does anyone have any concerns about melting/gluing PLA to complete things? I think it's pretty crude but saves a lot of messing around getting rid of support material. A tip I find is to never let the flame touch the PLA, and heat both parts to be connected at the same time with a bit of careful thought as to how to hold the parts, just as it starts to bubble I push them together and they are welded nicely. May be I'll add an updated file with taps & faucet built in the same object which doesn't need support if anyone says yes...
