Lexus Toyota 3-button Key Fob Case replacement
Found makerbotman's version of the old-style key fob. I wanted the buttons to be recessed a bit deeper, with a wider opening at the top, and while I was messing around, I added the logo versions, as well as a blank version. Choices are a good thing!
It looks like the key blades can be multiple sizes. I had 3 keys to make new remote cases for, in total, and each key blade was slightly different. The size difference isn't limited to side-to-side or front-to-back, so I also made the key blade retaining screw hole slightly deeper. This will require a new screw, and won't use the original screw, but it WILL hold the key in place. One of the keys rattled around in the recessed area in the Front, but the longer screw locked everything down and it didn't move. Shorter screws than the M2x10mm did allow it to move slightly, with progressively shorter screws allowing more and more movement
This will require new screws. I've settled on the Socket Head Cap Screws paired with a washer for all but the key blade screw. M2x8mm with washers (qty=4) for the 4 corners, and the key blade screw is an M2x10mm. I do not recommend anything other than hex screws, since these are so tiny and prone to rounding out or stripping the head of anything other than hex screws.
I printed this on a textured PEI bed, which gives it the texture seen in the pics. If your print bed will create a look that appeals to you (like this did to me), then I recommend printing this face down on your print bed. I tried this on a glass bed as well. Looked quite nice, but less forgiving IMO. When printing in the orientation I recommend, supports are not needed for the front part, but on the back part, the screw holes do turn out better with tree supports, which is why I listed this as needing supports. If you're okay with the results for the screw holes without supports on the back, it CAN be printed without supports, it'll just require some processing afterwards to get a nice surface for the screw holes.
If you print in any other orientation you will need to make your own decisions on supports, but that choice will necessarily require supports. I tried other orientations initially, and it will give you a nice face with the typical pattern your printer produces, but the edges of the key fob that mate together may not be as nice as you'd like them to be - for this reason, I recommend printing as I suggested.
Additionally, the logo is not very deep at all, and it was a happy accident that I realized it created the nice subtle inset look to the logo. The recessed logo is only 0.3mm deep, and the result with a skirt or nothing for bed adhesion is what is shown in the pics. When trying a brim for bed adhesion, Cura would add a bit of filament in the logo area and ruin the effect, so I gave up on trying to solve that issue - a skirt or nothing is sufficient.
Lastly, printing this at anything finer than 0.2mm would lose the logo effect. I didn't actually print this at 0.2, I was batching out my prototypes with a modded faster 0.28mm profile, which resulted in this look. I liked the look and results so much, I printed all 3 with this profile. I've included screen caps in the pics, of the pertinent info for the profile I was using. If you have better results with something else, or found a setting that gave you an interesting change to the look, please share.
