One indispensable resource so far has been the MP Select Mini Owners subreddit, which is surprisingly active. I was able to find the answer to several questions I had, from swapping heatends and nozzles, to printer upgrades and modding.
While waiting, I plan on brushing up on my box modelling skills using Blender, as well as putting together a list of parts I'd like to immediately print in order to improve printing results. Note to self...look through your spare parts for a 40mm fan to either add to or replace the one coming with the MP Select Mini. As it turns out, it is imperative to have efficient cooling for prints to come out well.
