Create a substration with a gap on the subtracted one

Hi, i wanna make stands for my resin vat, however i want to make a little gap to make easy to insert the « foots » on the vat. How can i make this ?

Hi! Are you looking to create a small tolerance gap between the two bodies? In this case, just create a copy of the purple body, scale it up by a few percent, then subtract it. The result will be a tiny (0.1-0.2 mm) gap between the two bodies which will make it easier to assemble them after manufacturing.
