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

thingiverse

This model is a re-creation of the metal addon slot bracket used in the Macintosh SE and a few other Compact Macintosh systems of the late 80s and early 90s. An original metal bracket was used to get the measurements for this part. The only major change between the metal original and this model is the walls were doubled in thickness from 1mm to 2mm to make the part stronger. I was not able to get a working part in either PLA or ABS at the original wall thickness. The part number stamped on the original metal piece is "805-0939-B NATD" If you find this part useful, a tip would be appreciated, thanks!
