Macintosh SE Addon Bracket (Apple P/N 805-0939-B NATD)

thingiverse

This model reimagines the metal add-on slot bracket used in the Macintosh SE and other Compact Mac systems from the late 80s to early 90s. An authentic metal bracket was studied to ensure accurate measurements for this replica.\r\n\r\nA key modification between the original metal part and this design is the wall thickness, increased from 1mm to 2mm to enhance structural integrity. Testing showed that a working part could not be produced with the original wall thickness in either PLA or ABS materials.\r\n\r\nThe part number stamped on the original metal piece reads "805-0939-B NATD".\r\n\r\nIf you find this design useful, a donation would be greatly appreciated!
