Intex Skimmer seal

I was given an Intex skimmer for a tubular swimingpool but it was not working properly.Upon further inspection, a seal was missing.In my case, the skimmer was totaly not efficient without the seal.People gave me the dimensions and I designed a first version and it worked.I designed a second one with smaller gaps and it works even better.I haven't compared to the original Intex seal, but this one might even be more efficient.
