These items i realise can be purchssed reasonably cheap however i decided to make them to gain a bit of skill along tbe way and learn .It also gives a sense of satisfaction to build your own gear
For me it is more of a financial thing. Why spend $20 - $30 for something if you happen to have a piece of stock to make it ? That money can then be used to buy stuff you can't make.
Plus there is the satisfaction of making something that works.
