Depending on which material you choose, you may want to add a raft or other bed adhesion structures depending on your printer. I made mine from both PET G and ABS which I normally don't require the use a brim or a raft. I did need to use support for the magnet recesses, but I found that no support also worked well for me. The magnets will be glued in place. ***Updated rev. The Lugger Rev. A, will need support. I will keep the older versions of this up as they require no support, the Rev A however will require support but is a nicer product.
