MakerBot Mini inside filament guide

pinshape

A simple solution for a common problem with the MakerBot Mini's filament guide. Our original guide lacked a crucial feature - a small lip to prevent the filament tube from sliding down into the print chamber. To rectify this issue, I created a replacement part that would serve as a stopgap measure until a more permanent fix could be implemented. The printed cylinder is surprisingly thin, but considering we no longer use the internal filament holder, there's little motivation to revise the design at this time.
