BSA30 ITA30 Bottom Brackets BB special installation tool ZTTO 12 notch

I received a bottom bracket from ZTTO BSA 30 but it wouldn't fit with the Race Face tool because it was too tight. I looked for a solution in this 3D design https://www.thingiverse.com/thing:3133772, but unfortunately it didn't work for me as I couldn't get the cup of the BB to fit properly. So I created my own design on my own with a conic/taper notch that would help fit it into the tool (1.5mm diameter at the top and 2mm at the bottom). To my relief, it fit perfectly but was still quite tight so I used a wrench to secure it in place. I printed it using PETG, with a resolution of 0.2mm, wall thickness of 2.5mm, and an infill of 30% gyroid. The design was made on Tinkercad.
