This is a nice puzzle solved by rotation

I have smoothed the edges and made alignment cylinders

just print :

2 Cross rotation (large parts) - align 4 holes upwards

4 small parts - align cylinders upwards

4 rods - align vertically (better use rafts)

1 lock (optional)

remember to install the rods BEFORE gluing it together!

Enjoy
