3dp burner pen

Needed parts ...............

a spare Arduino . I'm using a Uno

1 x pen holder
1 x pen lifter (if you have more than 1 ,it makes it easier for quickly changing pens)
1 x 9 gram servo (Tower pro or similar)
1 x 10k resistor
a length of suitable connecting wire
M3 nuts and bolts to attach pen guide

Stabilo pens that have an 8mm diameter

hot melt glue or foam double sided sticky pad
