About this 3D model

These are the 3D printable parts for my DIY solder paste dispenser design as described here http://letsmakerobots.com/content/solder-paste-dispenser I’ll be selling the PCB over at https://www.tindie.com later if anyone is interested. The PCB is now available here https://www.tindie.com/products/Dead_Bug_Prototypes/solder-paste-controller/
