That’s part of why I tagged @vicious1 up above, I don’t see the build instructions page on the v1e pages.
There’s s build thread with a video timelapse here:
It’s as described above, to provide clearance for a socket to tighten bearing hardware. You may not have difficulties if you have u-joint sockets or suitable extensions.
It is possible to modify the part to suit your printer’s capabilities and I know other users have done so (as @Bigchepin notes as having done).
Usually the advice is to look more carefully at why your printer can’t print the part as if it cannot then it may mean you have print issues.
For example, layer adhesion or cooling problems that may mean all of your prints are compromised in a way that will produce poor results for you.
There isn’t a right or wrong here. If you can get it to print for you and still assemble a suitably working machine then all is well.
The other reason I tagged Ryan was that elements like this go into the brainstorming for ideas to improve future versions of the machine.
