Petleh82 improved his Ultimaker. He added cheap Bluetooth module to enable wireless printing. He also stopped using blue tape on printbed and replaced it it with glass. To get PLA to stick to the glass print surface he coated it in mixture of wood glue and water. He successfully printed with nylon on glaass since it has problems sticking and warping on blue tape. Nice projects Petleh!
Check out previous post with a video on his one year with the 3d printer. He really shows how printers are useful and fun in everyday life:
