# Powershell, 77 bytes #

I must say I thought this would be easier with PowerShell, but it's quite hard to create something more condense than this.

`$a=@("/","\");"$(1..6|%{1..3|%{1..6|%{$a[$b]*5;$a[!$b]*5};"`r`n"}; $b=!$b})"`

More readable:

    $a=@("/","\")
    "$(1..6|%{
        1..3|%{ 
         1..6|%{
         $a[$b]*5
         $a[!$b]*5
            }
         "`r`n"}
        $b=!$b})"

I'm using the index numbers of the array in order to decide whether I should put `\` or `/` and between every loop I simply toggle the variable.
