I sure can, so i had a LC575 computer, damaged in shipment due to very brittle plastics. I could not repair it, so i decided to make a test stand with standard aluminium extrusion profiles, and 3D printed plastic parts to fit everything together. i can share those parts with you of course...

Haha, well honestly i am looking for a power meter that i can add, to keep an eye on power consumption. I suggest that to anyone fixing these things, its really handy to know what's going on, power consumption tells you if its in STBY, running well, or over-consuming due to a fault, a few watts...

Phunguss got you covered :-)

If you can get PETG material, the warping can be much reduced, the print bed needs to be at about 80C, but then the prints will not warp if you use good quality print materials

Indeed The lab is my home :-) Thank you sir!

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: Slide lock for internal swivel chassis motherboard support...

wow, so cool! you figured it out now, good to know ! that board looks pretty sad, so much damage. even the solder paste turns to cement under those conditions. reflowing will be needed all round, and resistor values can also change under these conditions. hope you can get it cleaned up and...

Best make sure the gap at the hinge is big enough for a layer of paint, without it rubbing against a surface, that would not look nice. i think you have about 0.5mm there to play with

Haha, i just drew one up :-) should have checked!

Caps needed: - 16V 2200uF 4X - 16V 1000uF 2X - 35V 470uF 1X - 25V 470uF 1X - 25V 47uF 3X - 50V 2.2uF 1X - 35V 100uF 1X - 25V 100uF 2X - 50V 47uF 1X - 50V 1uF 2X - 50V 10uF 1X if you can get it include the TOP200YAI and replace it, it seems sensitive.

I can already see that IC1/TOP200YAI is dead, R4, the fusable resistor is blown, meaning that IC1 is dead. this is the self switching fet for the standby powersupply, what you have there is 2 PSU's, one for standby and one for power. this is a common fault, sometimes caused by an issue...

Very smooth, looks nicer than extrusion printing, make sure you add a washer (nylon/plastic) in between the hinge part of the bezel where it meets the base (where the long M4 screw meets the bezel) id love to know what the print costs in total, and how the materials hold up over time, i would...

I have also drawn up the Motherboard supports and the Motherboard clasp as they are also crumbly print with 0.4mm nozzle at 0.1mm layer height out of PETG material

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...

wow, that took a while no doubt! always a joy when they finally do boot up!
