WAVE desktop tidy collection

An update of my Zigzag desk tidy, this collection now includes 5 different waveforms as desktop trays.

All are simple to print, and include minimal supported versions where required. You'll want to print about 180mm x 180mm for pens, or smaller for rings, batteries, screws or paper clips!

The 5 waveforms are:

• Sawtooth
• Sine
• Square
• Triangle (previously zigzag)
• Scallop

Feedback appreciated, and ideas for a second collection welcome!
