here is the file i think, i tried the remove all holes setting and it did clean it up, but didnt make it hollow. anyway have at it CE3E3V2_beck with base.3mf

as you can see the bottom of this thing i have wont correctly load in a way where it is hollow, i have all the faces correctly defined as well, anyway around this?

ill show you how it works out

good idea, i did think about that when i was doing it but the print is quite specific, but, i did think of a solution kind of, i dont mind swapping the filament twice per layer as it literally is going to be 2 layers, and if you are curious i am modeling a kill medal from halo. you can see what i meant, by literally only like 2 layers, and also this is what i have made so its hard to tell but its a few layer set down, so you get the reason why i want the outside one colour and the inside another, but i was thinking, if i wanted to i could slow the print down and then pause swap, and like i said i only have to do this like 2 times so i think it will be fine just slowing it down, or making it larger.

i want to customise the build path so that the outside of a coin is one colour, the nozzle goes over and prints a block, so i can pause the print, and change colours, and then come back, so the main goal is that the coin has one colour outside, and one colour inside. keep in mind i have an ender 3 v2 so i have to manually switch colours. is there a way to easily do this, or at least customise the travel path so i can do this, feel free to ask questions if you want me to be more specific.

could i have some help with a print, I'm kind confused why this is happening,(ender3 v2 btw)(cura 5.4.0) my print when scaling up doesn't work and instead appears grey
