Since I was going to fix 3 of these Powermac G3 beige PC's, I though I might as well draw up all the plastic parts I can print on my Prusa MK4S

Thus i drew up, printed and tested and adjusted and re-printed the following parts:

  1. Slide lock for internal swivel chassis
  2. motherboard support hook
  3. motherboard latch
  4. support column for swivel chassis support
  5. support strut for chassis
  6. support stand for swivel chassis
  7. support stand for power switch
  8. power switch knob assy
  9. HDD/ZIPdrive tray
  10. HDD tray receptacle (snaps in to steel frame)
  11. CD drive tray
What I didn't make is the level divider piece that sits on the swivel frame and the card holder, as they are too big to print on my prusa in one piece, but the rest is all there, printed, test fitted and verified parts, ready to print.

Print with 0.4mm nozzle at 0.1mm layer height with supports everywhere, and snap them right in place when done!

oh thank you so much, I just got a 7600 that failed the Fedex test with every single piece of plastic internally. Any chance you've modeled the level divider? the hdd has destroyed that side of the mount?

if it wasn't for the 3d printing 'tism, keeping these machines alive wouldn't be possible.

Appreciated.

IMO the only way to ship any Machines these days it to pack up TWO boxes. One with PSU, drives and anything else heavy and the cannibalized case in the other to prevent such borkage.

Be that as it may, I'm loving your BG3 parts modeling. I have several to patch together and pass on, knowing the folks on the other end can acquire your modeled parts takes a real load off! :)
