I designed these stands in Solidworks to put my WiFi Modem and External drive on, then I decided to make them stack-able with pins to hold them in place.

To be printed top down and pins should be printed flat side down Printed with on Tenlog D3 Pro, .4 nozzle, 4 walls, 9 top/ bottom layers 30% infill, Hatchbox Black PLA
