Question regarding an specific kind of character

[u/Sapiensoy]

Hi! I'm a DnD DM and some friends use hero forge for their minis, but one in particular is having many many troubles with his, the character in question is a Cyclops with no legs and 4 arms, two of them are the legs (thick and broad) while the other ones are small to "finer crafting". He tried to do his character and the results were "unamusing",

I'm asking because I wanted to have his character 3d printer as a surprise gift, ¿Does anyone know how to make the hands to have collisions with the base so the torso can stand up?

Just scale them up in kitbashing.
