IKEA pencil extenders

I acquired a bigger number of IKEA pencils but they are way to short to write with, so i designed these extenders. One is for one pencil, the other one combines two pencils at the back. 

The single-pencil extender prints without supports upright with a brim,

the dual-pencil-extender prints in a daring 45° angle without supports only held by a brim.
