Compact Macintosh Addon Bracket 805-0939-B NATD

[GiGaBiTe]

I remember a few people over the years needing the addon slot bracket used on some compact Macintosh systems like the SE, SE/30 and Classic. Now that I have such a system, I thought it'd be good to create a 3D model of it so it can be reproduced with a 3D printer.

The part number on my bracket is 805-0939-B NATD

Here's a 3D render of the bracket:

I'm currently printing one out now to see if the model I made is within spec of the original bracket as I had to make some estimations about certain dimensions.

If anyone needs one of these, let me know.

Here's first prototype:

It's almost perfect. One of the screw tabs is just a tad off and the part needs to be a bit thicker for more structural support.

Very good. How about some info on your 3-D printing setup in a new thread perhaps?

Dunno where I'd put it.

I have two 3D printers:

Tevo Tarantula
Creality Ender 3

I've put the final version of the bracket on Thingiverse:

The walls of the part are double thickness (2mm vs 1mm) because neither ABS or PLA is strong enough with such a thin profile. I carefully measured the part to make sure it would fit and it seems to be OK on my Mac SE.
