Dude, I was looking for something like this and it is amazing! Less cost, maximum efficiency. It doesn't feel cheap to craft and with their 1x1 positioning they suit my needs like a charm. Big vouch to put this little beauty in vanilla :D
ps. The mod doesn't standard work due to a file name problem, but after renaming the folder name to the one Factorio is looking for, it works like a charm! Many thanks!
