2-simple pen

I don't have it yet where I want to have it but the idea is already in the model.

It's a 2-simple pen because of the design from the outside it looks just like a tube but on the one side it has been designed to fit a Bic Crystall refill and it has been reinforced to ensure stability for the pen. 

The other end has a hexagon shape to fit a bit. Currently it fits a 4mm bit like you find in iFixIt sets. So you can use this pen as well to screw. The refill serves as a stop so that the bit doesn't fall through. When you put more pressure on the bit it's an easy and clean way to replace the refill. 

I am only at the beginning of my design journey but I wanted to continue learning. The design might not be stylish but I designed something sturdy. 

What is on my todo list however for this model is

• Make the refill insert smoother after printing now in need to remove some filament which covers the insert hole
• Make the hexagon slot a tighter its too loose and it should be a little bit tigther so that the bit doesn't fall out that easy.

Updates to the design will be posted as soon as they come available.
