Large Mans Cardigan Pattern

Can anyone help me with finding a large (3X) mans cardigan pattern that won’t be too difficult for a reasonable patient beginner for a Shetland Chunky? Obviously free patterns would be nice but I will order if I need to.

Here are a couple of easy ones, not man’s 3x, but unisex, I’m sure someone here can help you figure out how to increase to the size you need. I think I’ll make the first one for myself.
