Now on Tessa's Curated Boutique: @designlibero spider vase and lace vase (the 2 on right in top picture). Clever designs that upcycle a simple PET bottle into a vase. Buy the digital design (or have it 3D printed).
However, thanks to 3D printing, we have seen several very unique looking shower heads pop up on websites like Thingiverse and Shapeways. One designer, JMSchwartz11, took the original T-Rex head, and turned it into a brilliant shower head design. This will fit any standard 1/2″ shower head pipe, and should hold up nicely. Just be sure to warn your guests before they step into the shower!
3-D coffee cups. These are espresso coffee cups printed out of Glazed Ceramics. The printing process takes almost a full day, and the One Cup a Day project aims to design and create 30 unique cups in 30 days. You can purchase their creations from this website where prices range from $36 to $77.
