temp tower with clip - thin wall fix

No matter what I tried in PrusaSlicer the preview showed holes through the numbers. I tried several layer heights and settings... For a quick fix, I merged a cube to the back-side of the numbers. It does interfere with the cones on the back side, but only slightly. Sliced well at 0.15mm and 0.2mm layer height, for me
I only needed the 180C-220C & 200C-240C towers
