LM2596 Practical Mix

- Removed screw hole (I plan to use hot glue/adhesive)
- Strengthened tabs on lid as i had a few snapping (wider bases) (not sure what difference this actually makes)
- Hole ventilation design and buck converter type
- Redesigned wire holes and flat base for hot glueing or taping buck down flat

If you need to change voltage regularly, design probably isn't for you as i've not made a hole for it to be turned externally

My first share on thingiverse its not perfect
