    PowerBook 540c hinge restoration: SUCCESS!!!

    Finally I got Loctite 401 and glued the clip to the center cover. I left 24h before mounting and it looks very solid. It came in with a very satisfying click noise and stays in place properly. I printed it with a 0.2mm nozzle and set layer height at 0.1mm to achieve better resolution.

    Powerbook 520/540c Power Adapter repair/re-cap

    I’m facing a similar situation here, could you give me some tips to open the adapter case without ruining it? Thanks in advance

    I wouldn't mind printing these for free and just charge the shipping, but I'm afraid it will cost more and for sure take longer for you than if you print it locally. Besides, it's more ecofriendly

    There are several 3D printing shops, at least in my city, where you can go and they'll print it for you. But if you think you can make use of it, don't doubt and go for it. It's the best inversion I'd done in a very long time, it had paid itself several times.

    PowerBook 160 help (broken hinge mount)

    I've made a 3D printed hinge fix for both PB100 series and PB500 series. It was all posted in an another thread, I leave the link here:

    Finally, I finished the PB 100 series hinge fix. This one has been a little more tricky than the 500 series by some reasons, and I had to reprint it a few times to correct a couple issues. Some considerations: -Unlike the 500 series, the backpanel of the display isn't flat. This makes glueing the 3D printed part to the case mandatory. Otherwise, the screen has some free movement and when the lid is closed it opens a gap between the two cases. I couldn't get the glue yet, but I'm sure that glueing it will solve it. -The part must fit a two-leveled surface, 1mm a part. This forces to print a 1mm suport under the hinge area. No way this can be printed in PLA and get the support removed. I never worked with PET, but ABS is very easy to peel the supports, so I'd go with ABS for sure. Indeed it's easier to glue to the case if it's made in ABS. -About the threads: I've reused the thread inserts, so I could use the same screws, but note that I've inserted it BACKWARDS, so the thick part touches the case. This way makes it much difficult for it to loose. It comes in pretty tight, so I recommend to use a vice if possible. You might be able to insert it with pliers, but it could enter bent and break the plastic. Also make sure to remove all glue and plastic rests you may have in the threads. I burned it with a lighter and screwed the screw a few times to make sure the thread was clean. Also using this system reduces considerably the tolerance of the print, so the threads don't misalign with the hinges. Fortunately my printer is quite precise and I don't need to adjust anything before printing, but you should make sure your printer doesn't distort any dimension. There are some benchmarks on thingiverse to measure such distortion so you can adjust it before printing. I think that's all. I leave the link to the thing in thingiverse and some pictures of the process where you can see what I mentioned above. -I made the part to embrace the metal hinge, so the back panel shield won't fit anymore. I had to cut it with scissors leaving a little piece that will sit between the part and the hinge, still making good contact to the chassis. https://www.thingiverse.com/thing:4391026

    Update on the PB100 fix project, I've just finished the first attempt. I'll print during night and see if it fits. I alreasy glued the threads on my 170, I didn't remember. It's a question of time that I have to to it anyway, so I think I will remove all threads and test if the 3D printed fix works fine. I leave a picture of the thing.

    Yes, I'm digging in the Henkel and Ceys sites and it seems cyanoacrylate has slightly better resistance than epoxy. Thanks for the input!

    Mac Plus keyboard with poor connection

    Are you sure both cables are specific for the Mac Plus? @trag is right here, you could damage both thing as wiring differs from a standard phone cord (Apple things). I can get a picture of my Mac Plus cable when I get home for you to compare

    The big deal here will be the glueing part. It will be a lot weaker than the layer adhesion. I won't go cheap on the epoxy, I'm thinking on this: https://www.mundoceys.com/storage/app/media/fichas_tecnicas/510106 HT ARALDITE STANDARD.pdf I'm sorry, I couldn't find an English version, but if you look at the graphic measuring resistance in MPa, it has the best values for ABS and Polycarbonate I could find. If you have a better recomendation, I'm listening.

    I think I could do something. I'll get on it when possible and post both here and on the pinned thread.

    I came up with two designs that may work, I haven't tested yet as I don't have epoxy glue right now, but both fit well. The first one fits between the two broken clips (you need to cut them flat). The second has a large glueing area, but requires to remove both clips completely and centering the piece by hand. I've just posted them in the same thingiverse thing, link below. I'd print it in ABS, due to its better glueing capacities, and using a 0.2mm nozzle if possible (pictures are printed with a 0.4mm). I'll let you know when I get the glue.

    Send me some pics to see the problem. I have a 170, so I can get the measures myself.

    Mine isn't broken luckily, but I can give it a try and see if I can make something.
