Have you tried openscad ?
your part would take about 3 minutes and 4 lines to design.

Plus you could make it parametric.

For practical things openscad is probably the best and easiest to use.

You don't draw anything you just tell the program what you want and it does it for you.
With the added bonus that it only makes solid models that are suitable for 3d printing.


Does the v-cut in the tip go all the way through the tip, or is it just on the one side ?
The pictures really don't make it clear.
sketch-up - not so much :-)
