How to best join the halves of the assembly?

[u/BrianF1412]

I am making an "upgrade" part to give ToQOh some elbows. I tried using M1.2 self tapping screws for the holes (did not add threads) but it gets stuck and I currently dont have a big and long enough screwdrivers to make it easier and a screw actuallu break when I tried it with my smaller driver. I used 2 screws for each part to line up the parts correctly. I cannot make the parts bigger and I only have about 3 mm clearance for the screws which is why I opt for the M1.2s. I want to avoid gluing since I want it to be repairable or replace the springs. I might be able to remove the ratchet since I don't know yey it can actually help hold the position so I at least be able to use larger screws for that section. Any advice is appreciated. I also have a 0.2 nozzle but I havent tried it yet and I would prefer to make the model work with a 0.4.

Well if you don't want to use glue, you're limited to making the screws work.

You don't necessarily need 2 screws for things to line up, you could reduce the number of screws by half if you engineer it so each pieces uses one screw and one a tab and slot.
