V-Slot Mini Carriage
thingiverse
Built a mini carriage for my side table that I built out of vslot extrusions for fun. I used 4mm bearings I had around for the base of the wheels. The base plate I designed with a quarter inch hole so I can attach my articulated arm to hold my phone while I'm programming. Freecad source is available, so feel free to create your own plates to create a carriage to suit your needs. Some hardware 20mm long M4 screws and nuts 4mm x 13mm x 5mm Ball Bearingshttp://www.amazon.com/gp/product/B00AUB7M3C/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1
