Simple Ikea Skadis Hooks and Arms

I designed some quick, and easy to print hooks and arms for my Ikea pegboards.

There are 2 different sized hooks, and 4 different sized arms. The longer arms are reinforced with a diagonal member. 

I print them with enough walls to make them solid, (usually 5) so infill in not necessary. 

I have not done any strength tests, but i print mine in PLA and have not had any issues with breaking.
