I haven’t used vagrant + virtualbox for a while and an error shows up when I tried to reuse.

I have googling about it and I found solution.

sudo /Library/StartupItems/VirtualBox/VirtualBox restart

But I got different error when I tried this.

sudo: /Library/StartupItems/VirtualBox/VirtualBox: command not found

And I have checked vagrant version.

vagrant version
Installed Version: 1.9.1
Latest Version: 2.2.3

I found my vagrant version is quite old. So I have downloaded new vagrant file and reinstalled. You can download updated version from Vagrantup.com

Also I have upgraded Virtualbox as well.

Then Vagrant start working as before.

$ vagrant up

It’s always good to have things are updated.

I recently bought 3D printer and I designed extra helping hand for soldering iron.

I used tinkercad.com for design 3D modeling.

Here is what I have designed.

And printed this out using Anet A8 printer.

And here are the parts printed out.

Assemble these together.

It can hold solder rill and anything.

Like this.

It will be useful helper when I am making DIY projects.
