755c PCMCIA Cover

I made one. It's more basic but fits and does the job perfectly. It's different to the one in the 760.

The side profile of the ThinkPad 75x/76x is not perfectly vertical; it has a tapered design (wider at the top and narrower at the bottom). To achieve a flush fit, you may need to set the angle between the faceplate and the latching rails to 85 degrees (a 5-degree offset from perpendicular)





I shared a 3d model before, and here is the TinkerCAD link

75x and 76x are slightly different but it's easy to remix based on this one.

Your one doesn't fit the earlier 755c/755Cs - if you look closely, the 755c one i've shared has two notches which are the first signs it's completely different.... As you may recall the early 755C and 755Cs share more similarities with the 750 than the later 755 range - different insides, no volume control dial, different screens, different PCMCIA covers... and the 750 PCMCIA cover is the same on the 755C.

I'll look at this 85 degree thing, however the one I've made does fit pretty flat and flush. I copied an original and because of it's inserted position, the degree angle of the side of the base would make no difference...

Cool! Thanks! Does it fit 360 series? Looks very similar to me.

I looked at the 360 base and it uses the same PCMCIA cover as the later 755s, not the 750/755C/Cs - so use the one provided by @panips and you should be good.

I checked and tested the 755c cover, it's in fact 3 degree (tan3' is about 1/19), which is exactly what I have used. So it's easy to create one by adding two notches (holes of trapezoidal platform).

For such a small part, it must be created accurately to fit the original laptop perfectly, that's why I managed to have a 1:1 replication accurate to 0.1mm. BTW: SLA/LCD can get you a perfect replica, but FDM 3d printing would not.
