I'm looking for way to draw the \vDash or the \models operator but with three horizontal lines instead of just two. Is there an easy way to do this?
It should look something like this:
Thanks for any help!!

We can scale the symbol to the height plus depth of the summation and then vertically center it with respect to the formula axis.
\documentclass{article}
\usepackage{amsmath}
\usepackage{graphicx}
\makeatletter
\DeclareRobustCommand\bigop[1]{%
\mathop{\vphantom{\sum}\mathpalette\bigop@{#1}}\slimits@
}
\newcommand{\bigop@}[2]{%
\vcenter{%
\sbox\z@{$#1\sum$}%
\hbox{\resizebox{\ifx#1\displaystyle.9\fi\dimexpr\ht\z@+\dp\z@}{!}{$\m@th#2$}}%
}%
}
\makeatother
\newcommand{\bigstar}{\DOTSB\bigop{\star}}
\newcommand{\bigA}{\DOTSB\bigop{\mathrm{A}}}
\begin{document}
\[
\sum_{i=1}^n\bigA_{i=1}^n x_i\dots\bigstar_{i=1}^n x_i
\qquad
\textstyle
\sum\bigA\bigstar_{i=1}^n x_i
\qquad
\scriptstyle
\sum\bigA\bigstar_{i=1}^n x_i
\qquad
\scriptscriptstyle
\sum\bigA\bigstar_{i=1}^n x_i
\]
\end{document}
A simpler but not not scalable version (it won't work in
\newcommand{\opA}{\mathop{\vphantom{\sum}\mathchoice
{\vcenter{\hbox{\huge A}}}
{\vcenter{\hbox{\Large A}}}{\mathrm{A}}{\mathrm{A}}}\displaylimits}
In this way the "A" will be as large as the \sum symbol.
An enhanced version, where one can specify a correction factor for the big symbol in display style, as different symbols seem to require different factors.
\documentclass{article}
\usepackage{amsmath}
\usepackage{graphicx}
\makeatletter
\DeclareRobustCommand\bigop[2][1]{%
\mathop{\vphantom{\sum}\mathpalette\bigop@{{#1}{#2}}}\slimits@
}
\newcommand{\bigop@}[2]{\bigop@@#1#2}
\newcommand{\bigop@@}[3]{%
\vcenter{%
\sbox\z@{$#1\sum$}%
\hbox{\resizebox{\ifx#1\displaystyle#2\fi\dimexpr\ht\z@+\dp\z@}{!}{$\m@th#3$}}%
}%

\makeatother
\newcommand{\bigstar}{\DOTSB\bigop{\star}}
\newcommand{\bigA}{\DOTSB\bigop[0.92]{\mathrm{A}}}
\newcommand{\bigDelta}{\DOTSB\bigop[1.05]{\Delta}}
\begin{document}
\[
\sum_{i=1}^n\bigA_{i=1}^n\bigDelta_{i=1}^n x_i\dots\bigstar_{i=1}^n x_i
\]
\begin{center}
$\textstyle
\sum \bigA \bigstar \bigDelta_{i=1}^n x_i

\sum \bigA \bigstar \bigDelta_{i=1}^n x_i

\sum \bigA \bigstar \bigDelta_{i=1}^n x_i

Superimpose a clipped raised \bot to \bot:
\documentclass{article}
\usepackage{amsmath,trimclip}
\makeatletter
\DeclareRobustCommand{\Bot}{%
\mathord{\vphantom{\bot}\mathpalette\mich@Bot\relax}%
}
\newcommand{\mich@Bot}[2]{%
\ooalign{%
$\m@th#1\bot$\cr
\clipbox*{0pt 0pt {\width} {.5\height}}{\raisebox{.2\height}{$\m@th#1\bot$}}\cr
}%
}
\makeatother
\begin{document}
$\Bot \bot$
$\scriptstyle \Bot \bot$
$\scriptscriptstyle \Bot \bot$
\end{document}

The
turnstilepackage is designed for typesetting various configurations of turnstiles with or without text above and below the bar.For your case, you want a single vertical bar on the left followed by a triple horizontal bar, and no text, so the command is
\sttstile{}{}:
