Looking at building one of these for my club and noticed, as the title says, that the "Cylinder Left Side" has countersunk holes for Cap Head Bolts. A parallel sided hole would be better for them.
If you're using the taper only to aid printing then you could place a two-layer thick membrane to close the top of the parallel sided hole (0.24mm thick would do for 0.2mm and thinner printing layers) which would be bridged over. This can then be cut-out at assembly time with an appropriate drill.
I know this is additional work but it's not really a beginner's project to build one of these.
