With the release of both my remix of The Wiper V2 and Maleko's The Wiper V3, I had to adjust my silicone mold to the appropriate size. My remix uses a wiper cut to have 5 nubs but Maleko's requires only 4. Therefore, this model will allow you to make either 1 or 16 silicone wipers with 4 nubs on each.
I used some clear 20A silicone and have seen good results. My X1C came with a small tube of Silicone glue for reinforcing connections but I find that it works great holding this little wiper down as well.
