Sadly most people in this keyboard forum seem not to be able to read.
The OP clearly states, that he is going to make one of a kind keycaps with custom design, as long as it is simple enough. Still you haters come *****ing about this beeing a CC ripoff and claims of beeing overpriced, when he gave a range for the price, which obviously will depend on time and material costs, but everyone just quotes the highest boundary and complains about it beeing overpriced.
Btw its his time he puts into making these, so it is his choice to put a value on that time and if you don't like it don't buy it.
And also it is absolutely fine to recreate a design by yourself (even a protected one) for non commercial usage. So showing off his CC style keycaps, so you ppl get an idea what he can do is also a non issue.
