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).
Tube Roller - An adaptation of alany's tube key http://www.thingiverse.com/thing:21410 that includes a squasher frame and end cap to hold the key in place. The slot in the squasher is offset to help the tube go around the key.
