5th Gen 4Runner center console storage cubby phone mount magesafe mount

I had created a Similiar mount but with one arm and it was wobbly. So this is my attempt at a vibe coded dual arm 5th gen Toyota 4runner phone mount that fits in the center cubby. It maintains storage space but provides a convenient spot for the phone to sit.

Currently it is held in with friction i placed a Livestrong style band around the base of the cubby and it holds it securely. But longer-term, i think adhesive Velcro on the bottom would be better. I also fed the USB-C charging adapter next to the cubby and into the center console. 

The original phone mount was a remix of this: https://makerworld.com/en/models/1255777-iphone-pro-max-magsafe-ram-mount-remix it just cut it and extruded in 3dbuilder and made a hole for an m6 screw.

There is now an OpenScad version of a phone holder where it has the screw hole recessed already and you can customize the arms, width, length, etc that should work just fine.

I printed the arms laying in an orientation for strength which required a lot of support and it likely isn't needed.

CUBBY + ARM ASSEMBLY

========= UPDATE 05/27/2026 ==============

• Switched from Threads to a Spline System: Replaced the threaded peg with a 24-tooth indexable spline gear. This allows you to drop the arm on in perfect 15-degree increments without fighting thread pitches or wobbling.

• New Offset Parameters: Added arm_x_offset and arm_y_offset so you can shift the entire upper arm assembly further away from the shifter.

• M3 Set Screw: Added a 2.8mm pilot hole to the back of the arm base. Drive an M3 set screw into it to lock the arm vertically to the peg.

• Tolerance Tuning: Added a peg_shrink parameter so you can dial in the perfect friction fit without having to reprint the large cubby or arm pieces.

========= HOW TO ========================

Customizing & Rendering:

• You can render each part individually by toggling true or false in the "1. RENDER TOGGLES" section at the very top of the code.

Tuning Tolerances:

• If the spline is too tight to pull out, increase the peg_shrink parameter (e.g., to 0.3 or 0.4).

• If it wobbles, decrease peg_shrink (e.g., to 0.05 or 0.1).

• Then reprint the peg and try it again.

Assembly:

• Drop the Arm Body onto the peg at your perfect viewing angle.

• Optional: Apply a few drops of superglue to the bottom half of the peg and insert it into the Cubby Base for a rock-solid, permanent anchor.

• Optional: Drive an M3 set screw into the hole on the back of the arm base until it bites into the peg to lock it down.

Print Settings:

• Supports: None needed. You can print everything exactly in the orientation they render on the screen.

• Walls/Infill: Whatever you prefer. I used a high wall count on the spline.

• Seams: For the splined peg, use staggered inner seams and set the seam position to random so it doesn't create a bulge on one of the gear teeth.

MAGSAFE PHONE HOLDER

========= UPDATE 05/27/2026 ==============

• Anti-Rotation Sockets Added: Integrated four shallow cone pockets on the back face. These perfectly mate with the anti-rotation dimples on the Y-arm hub, locking the holder in place so it cannot spin once tightened down!

• Tuned MagSafe Puck Fit: Slightly adjusted the puck pocket diameter for a better fit charger. Could still be tightened up a little.

• Refined Hardware Tolerances: Widened the center screw head counterbore to 12.8mm and deepened it to 4.2mm to better swallow standard M6 bolts.

========= HOW TO ========================

Customizing:

• All of the adjustable dimensions are neatly organized at the very top of the file. You can easily tweak the side-arm gap, the puck size, or the screw clearance to match your exact phone case and hardware.

Print Settings:

• Orientation: Print it flat on its back

• Supports: None needed! The cutouts and arms are designed to bridge and build cleanly without support material.

• Walls/Infill: 3 or 4 perimeters/walls are recommended to give the side arms plenty of flex-strength so they don't snap when snapping your phone in.

Feel free to remix and improve and provide feedback.
