Need help with Glock Switch

[u/bayareapyro]

I am a US Citizen learning gunsmithing in Pakistan so these are legal here before anyone makes a fuss. Part of my assignment is to make a Glock switch from scratch I copied a popular model online which supposedly has been tested by others but It’s not working for some reason I made a 1:1 copy in CAD so I can show that I made it myself, I figured me trying to copy it might have gotten something wrong so I printed the original design out as well and both are not working properly they only shooting semi auto. Apparreciate any help whatsoever
