Block for SPPJ225800 DPDT push button

I wanted to add push buttons to my guitar to incorporate parallel/series switching, but can't afford a James Tyler and buying the parts to install this was a bit expensive because I'm not in the USA. I initially used AI to copy the specs for the block on this website: https://www.stratcat.biz/smb-rev2.shtml , but that didn't fit the block or the cap so I started again from scratch. The push button's specs say to use M2 screws but I found that they're too big so I've used m1.7 screws. Fits with C&K FG push button caps, an example of which can be seen here https://www.digikey.co.uk/en/products/detail/c-k/FG-RD/417525 . Holes might need a little reaming to make them smooth and let the cap move without sticking to the sides.
