As i have limited space and my cord ws bended i create holder with 45° angele to make more room to keep them away from bending. One side keep screws hided and that should be put first then after put inside extension i add second part and screw it. Parts can be mirrored, paart with space for power cable iprint with supports and it work without problem, also i add test file to check how it fit to extension before print rest.
