Hi there All,

I have a Power Macintosh G3 in and the plastics are very crumbly, so i have spend a few hours to make the needed parts in CAD and i have test fitted them. a few revisions down the line, they are ready to print.

Here to share:

- HDD slide in brackets (the ones that live on the metal frame)
- Slide lock to lock the swivel frame in place
- HDD bracket for mounting to the drive

0.4mm nozzle, 0.1mm step height, ideally PETG material print with supports. please check slicer image for best print orientation.

Happy printing!

Arjen.

I have also drawn up the Motherboard supports and the Motherboard clasp as they are also crumbly
