These are 3D rendered arm cannon attachments for a model kit, Specifically the Mega Size 1/48 scale Gundam RX-78-2. The model itself isn't inherently mundane; however, it's a decoration on my desk that I don't play around with often. due to its size, Accessories are bog standard, so i thought why not make an attachment for it? Luckily enough, this thing has attachment points already with a 8mm standard peg connection on the arms
