Insane milestone 9

[thorn kettle]

I have spent hours trying to figure out insane milestone 9 shape {RmCcWcCm:--cm--cc:RcccCmcm:cmcccccm:cw--cw--} but cant seem to do it. I have only figured out 4 of the layers, but not the fifth, as it feels impossible to create without shattering the crystals that are already on the fourth layer or shattering the fifth layer crystals when i try to stack them on the fourth layer. So must i somehow create the layers top to bottom? Image shows how i managed to make the first 4 layers

as a first hint, you have to create the shape column by column and not layer by layer, you can also then check https://shapez2.wiki.gg/wiki/Shape_Patterns#Gap:Shape:Crystal
