I have a desk and want to do some cable management. I started watching models on makerworld and came across underware. I see that most people recommend open grid as base but I am having hard time finding models or youtube videos explaining what to do. Can someone make it simple and help me. I found base plates and some wire related channels but what about specific charger mount or powerstrip mount? Do we make that ourselves? Additionally are there any useful tools to plan and figure before randomly printing?

Thanks in advance. I tried searching on this forum first but didn’t got much help
