How to increase the wall thickness of this shelled object?



I am making a series of phone objects and it has become apparent through use that this particular receiver needs a thicker shell to make for a stronger 3D print. Ideally I would still have the solid, pre-shelled version of this, but alas I do not. What is a recommended approach here? I thought about ‘casting’ it using some boolean operations and re shelling it, but would rather not have to rebuild internal geometry. Perhaps that is the price I pay for lack of planning and version control.

Hi Revel - Shell or OffsetSrf > Solid=Yes should help.

Thank you, I will look at that now. realize I forgot to post the model, here it is (9.7 MB)


@pascal would you mind elucidating a bit further how precisely these commands will help me thicken the shell of the above model?

Ah, I see, it is already shelled, you just want to make it a thicker wall, correct? That is definitely less straightforward - see if the attached thing is anything like what you need - I thickened the overall ‘main’ walls but offsetting the inner surface a mm or so and extending/ retrimming all the details to suit. Basically blow it into surfaces and deal with it at that level then reassemble the bits. No magic…

Ah yes, ok, thats what I was afraid of! i suppose its a bit silly to think there was a magic button for doing such things. Thank you anyway! -rev
