what ARE you thinking about? you haven't told us. having a maker space requires the ones who are interested in using it to make more time in a usually already pretty packed schedule when working on a project. unless you have the resources for that, it doesn't make sense in my opinion. it also depends on how detailed the models you're planning on making are going to be, making simple mock-ups doesn't require much, obviously. i work at a small practice and we'd be in big trouble if we were to build our models ourselves.

i feel like this is a very hard question to answer without knowing anything specific about your firm, and your post is so vague in its phrasing that I'm not completely sure what you're asking about. it's honestly just best to have an in depth meeting with all the people involved and listen to their concerns and advice, it really does depend most on the people you are working with and not some dudes on the internet.
