I know some folks DIY, but the HangAir wetsuit dryer is probably some of the best $50 I've spent on surf accessories. Use it constantly.
I have this hanger with built in fan. Works great. I hang it right after surfing. About an hour after I squeeze the legs and arms to get most of the water out and the wetsuit is 90% dry before I go to bed. Maybe just a little damp at the ankle area. If you leave it on for 20 hours it will be dry. And it’s hanging in my garage where it’s cold in the winter.
