Generic removable car interior ceiling pin.

Dimensions:

• Hole diameter : 8mm
• Head diameter : 25 mm
• Thickness of ceiling: 6mm

Ask me if you need STLs with other dimensions, I can add any size easily. Or if you prefer, customise it yourself in Onshape: https://cad.onshape.com/documents/c7b576886b9d228fec9c8d6d/w/ffa24ec69b7bea32989cfa04/e/3e437685f55bce141b3fd814

White ABS print of this one fits my Peugeot Expert just fine, cannot tell it is 3d printed :) I tried to break one by pulling on the pins and the head and I could not. I will see how it handles the real use case in my car now...

Printing:

• There is a support STL object included that works better than slicer support. Activate "print thin walls" (Cura name) so that it prints completely.
• Have your "Horizontal Expansion" (Cura name) setting calibrated so that a X mm cylinder will fit into a X mm hole. This setting could have an other name in slicers other than Cura. A typical value for FDM printers is around -0.1mm. A more negative value will give a larger clearance. This point is important as there is very small clearance in the object dimensions. So, either try with -0.1mm or calibrate your Horizontal Expansion setting with the following: https://www.thingiverse.com/thing:4905876

I designed a simple non-removable ceiling pin as well: https://www.thingiverse.com/thing:4937279
