I know you’re mad about it. Yes you do, don’t deny… These damned missing rubber feet on your beloved Alum PowerBook are making you mad. Arrgg… What to do ?… Order a set at in the US (I’m in France) just to get 4 of these ridiculous pieces of plastic, when I need about … ten… at … WHAT ?! 15$ A SET PLUS POSTAGE ?! I’m mad but not THAT much.   Then , thanks to Dandu from the journaldulapin.com blog, I learned about Sugru. That is mouldable paste that turn into rubber like material once dry. And it’s available in a medium grey colour very similar to the one used by Apple on various pieces. it’s not too expensive at 8€ for 3 small packs.     Anyway, did myself a mould of an original feet with hardening modeling paste and pressed some Sugru paste on in. With rest of the Sugru , rolled two "boudins" (sausages, not to be confused with "petit boudins"…) from which I would cut some feets if the mould idea didn’t work. And You have to use that Sugru once the pack is opened cause it's not savable.     that’s what I did in the end , cause the ones cut from the "boudin" looks better… Then glued it in place with a drop of SuperGlue (works surprisigly well on Sugru).     Voilà. Don’t know how long it’s gonna last, but better than no feets. And I still have material to make replacement. Thank you for reading this small handycraft moment.   Note: This Sugru thing looks very much like rubber , I think it could be used for other Mac rubber pieces replacement. For example these rubber bumpers on top of the PowerBook 100 screen lid… If one have a good original example from which to make a female mould, then press some grey Sugru in it, think it would work. Maybe would need some demoulding agent in the mould to remove the Sugru once dry though, cause it tends to stick to the pieces…
