Summary

An insert for the cup holder in a 2002-2006 Toyota Camry (most models, I think) that facilitates securely holding smaller cups or bottles. The original part seems to wear out and fails to stay in place. They are difficult to find in the used market and those that you can find may be worn out already and/or are quite expensive. There is currently a 3d printed design available on ebay, but it appears to be not overly attractive and has some negative reviews for functionality.

This one is made in three main parts plus two little pins which hold it in the cup holder and provide the axis on which it rotates between the up and down positions, where it is stowed, or used, respectively. It is partially assembled in-place; please take note that it is a bit fiddly to install. This is sub-optimal but it does then stay in place with no chance of falling out unless something breaks.

The current version uses 6 screws in the assembly. It might be nice to have a version using snap-fit connectors, but I didn't find, or want to spend the design time for, any that would fit within a space of about 2.5 mm as would be necessary. This might be a nice extension as might be rounding some of the corners and edges. The weak point of this is probably the pins and they could be replaced by metal screws, bolts, or pins, but then they might wear-out the holes into which they are inserted.

Printed in ABS and TPU.

Notes:
The top, bottom, and two little pins were printed in ABS with the middle "pad" portion that actually contacts a cup, printed in TPU. I don't have any reason to believe that PLA or some other material wouldn't work fine for the pieces other than the middle one.
I used a textured PEI sheet with the visible surfaces of the top and bottom pieces down on the sheet. I used a smooth glass sheet with the top surface of the middle piece placed down on the smooth fiberglass.
Tree supports were only used to help keep the shape for the holes for the pins.
Because the holes in the cup holder in a car might have experienced different degrees of wear or for other variations in dimensions, it might be advisable to first print the pins and the top piece and do a trial fit in the car. If changes to the pin dimensions are necessary, make those in the .scad file, and the required modifications to the other pieces will be done automatically. Once the pins and top piece are satisfactory, print the bottom piece (also out of hard material) and the middle piece, out of a soft material. A final suggestion, if trial pins are used, is to make some pins with long 'handles' which make it easy to manipulate them to ensure they fit the holes in the cup-holder. Or maybe you have daintier fingers than I do.

Post-Printing

Finishing/Installation Instructions:

Open-up/round holes for pins. I used a 1/8 inch drill bit. Be careful as you are drilling into small holes in parts made of plastic.
Tap or otherwise create threads in the screw holes in the top and bottom pieces. Be careful not to push through the top of the top piece. I used an M3 x 0.5 tap to match the screws.
Install pins in the holes with the heads on the inside of the top piece and the shafts going through the walls, pointing outside, so that they would be in place in the holes in the cup-holder in the car.
Place the middle piece on the underside of the top piece, aligning the holes provided with the bosses containing the screw holes.
Push the pin heads up against the wall of the top piece so that the pins are in their most extended position. Place the bottom piece on the middle and top pieces so that the pin-retaining blocks fix the pins in place in their final positions.
Insert two screws, from the bottom of the bottom piece up into the top piece, on one end of the insert. This will permanently hold the pin on that end in its final position.
In the car, probably working from the passenger side, maneuver the insert into its position in the stowed configuration, and place the secured pin into its corresponding hole. The bottom of the bottom piece should now be facing you and the tips of the soft pad should be pointing up toward the ceiling. One end should be in place.
Gently bend the free end of the bottom and middle pieces away from the top piece and allow the pin on that end to move such that none of it extends beyond the wall of the top piece. Maneuver the insert into its final position and then, using a slender tool (screwdriver, allen key, bicycle spoke...) push the pin through the wall and into the hole in the cup holder.
When the pin is in its final position, squeeze the top, middle, and bottom pieces together and insert a screw into one of the two screw holes on the end of the insert.
The insert should now be held in place and its operation can be checked, gently flipping it up to the stowed position or down to its position when in use.
Insert the remaining 3 screws. When inserting each screw, apply enough force so that the bosses from the top and bottom pieces touch and the screw holds them together. However, don't use any more force than necessary since you are working with plastic and the screws could protrude beyond the top of the top piece.

How I Designed This

I designed this in OpenSCAD from measurements taken from the broken OEM piece plus several trial-and-error modifications. It is designed to be installed in-place so that it is held securely and will not fall out. The pins hold the insert in the car, the retaining blocks hold the pins in place, and the bottom piece, containing the retaining-blocks, is held to the top piece via the screws.

Requirements

I used 6 screws:
Black oxide steel M3 x 0.5 x 6mm long.

Also useful was an M3 x 0.5 tap. If the entrances to the holes on the bottom surface of the bottom piece were tapered a little (I didn't do this) or countersunk a little, the screws themselves could be used to create the threads.
