Toyota Corolla Rear Seat Release Handle

prusaprinters

This is a replacement rear seat fold-down handle for an E120 (~2002-2007 depending on where you live) Toyota Corolla hatchback. It's the small handle you use to release the rear seats so they can fold down and expand the boot/trunk size. I designed this for a friend who had lost the handle on the right (driver) side and was having trouble operating the small metal lever the handle clips on to. The part is a direct push-fit replacement, just print the part as directed then push it onto the metal lever till you hear/feel a slight click. It should then be locked pretty firmly in place and can be used to operate the rear seat release. Feedback and remixes are welcome. Print Settings Printer Brand: Creality Printer: Ender 3 Pro Rafts: No Supports: Yes Resolution: 0.2-0.12 Infill: 10-20% Gyroid or Cubic-Subdivision Filament: Generic ABS Black Notes: Suggest around 8 top/bottom layers as the sides are tapered and at finer layer heights especially it's easy to penetrate them if you're sanding or vapour-finishing the part. Likewise you'll probably want 3-4+ walls/shells for the same reason. Raft is not required provided your bed is levelled and you have everything dialled in for good first-layer adhesion. The main handle is slightly tapered towards the top so there should be a small support under part of it to help build the taper. I printed using zig-zag supports with grid interfaces top/bottomeverywhere. If you have confidence in your printer's bridging ability you may be able to get away with supports only touching the build plate, but for more reliability put them everywhere. Make sure you have sufficient z-gaps above and below the support to make it fairly easy to remove from inside the part. I used 0.24 top and 0.36 bottom z-gaps for the supports (w/ 0.12 layers) and they all came off quite easily. ABS or other higher-temp filament is recommended over PLA, especially if you live in a warm climate where the interior of a parked car might get quite hot. Here in Australia the interior of a car parked in the sun can easily reach 50-60C+ and PLA will likely start to soften and deform. If using ABS a heated is a must, and ideally an enclosure to keep the ambient temp high, but if like me you don't have an enclosure Cura (and possibly other slicers) have a draft-shield option which can help keep the part evenly heated during printing. Post-Printing Finishing The part can be used without any finishing steps, just remove any supports and it should clip straight on. If you wish you can sand/file the edges of the handle a little to round them off and give it a nicer feel. Acetone finishing is also an option, but take care not to over-expose the clip to the point it weakens or deforms. Straight off the printer with supports removed and no finishing Finished print showing the Cura-generated draft-shield still in place which helps prevent ABS prints warping or de-laminating How I Designed This This part was designed using Fusion 360. I took measurements from an existing part, sketched them out and extruded accordingly. Minor tweaks like putting a draft angle on the handle were done, but most of the work was accurately measuring the original part. In this case the existing part was the left-hand version and the right-hand part had been lost. Fortunately they are identical aside from the clip which is on the opposite side, so when placing the cut-outs they were just put on the corresponding side. Fortunately this worked and it fit from the very first test print (a rare thing, for me at least!). The right-hand version was created by just mirroring the clip portion of the part.
