DIY: Cheap (and apparently) Stylish RGB LED Lamp for $15

One of the great things about 3D printing and hobby electronics is that you can often get 90% of the style and features of an expensive product for 10% of the cost. Take the Philips Signe lamp. It's a good looking RGB lamp - much color, look nice - but at $250 for the floor model it is something I would never purchase.
However, with some very basic 3D design and even more basic electronics we can get most of the features and a similar style for a fraction of the cost.

If you wanted to make a larger 12v version consider trading in the 5v LED strip for a 12v LED strip, powering it off of a 12v wall wart, and using a buck converter to reduce voltage to the 3.3v required for the esp.
The buck converters I'm using are these: www.amazon.com/gp/product/B01...

What is the point of carving out the back of the PVC? LEDs will shine through them quite nicely. Or is that a feature of the Signe lamp I don't see? Thanks! (printing parts now!)

The PVC will let a little light through but not nearly enough to be a 'lamp' of any kind. If you were only going for accent lighting or subtle path lighting the shine-through might be enough.
