I would like to make a shorter version of $\sqcup$ to use as a symbol for a Turing machine if possible. The first picture is the height I would like it to be and the second is the default height. enter image description here enter image description here

One option, scaling down vertically the symbol:




$\sqcup q_{2}\quad \ssqcup q_{2}$

One can reduce the vertical size; the scaling of the horizontal line will not be noticeable.



$\tsq q_2\mathtt{0}$

With \bm the symbol will be blacker.

If you don't need the symbol in subscripts or superscripts, omit the \text around the main body.
