Shorter CR-6SE topmount spool holder

My CR-6SE sits in a cabinet which used to house a rigidbot. The side-mounted spool on the CR-6SE makes it markedly wider than the Rigidbot, and the original top-mounted spool holder by Miller_Maker sat too high to fit in my cabinet. A little fidgeting with Tinkercad, and now this sits low enough to sit inside my cabinet, and it doesn't interfere with the X gantry at all.
