Ốp Lưng Fold 7

2025-08-26

New model files uploaded. Tweaked a few things but notable changes are as follows: 

• The cutout for volume rocker and power button is smaller and the matching curvature for the front case changed to match. I still need to make some tweaks to this as I get a weird step a couple layers from the top. 
• The mic cutouts should now be more centered and the shape is more round. Might need to shift the USB-C port cutout over a fraction of a millimeter to perfectly center it in the next version. 
• Reduced the width of the overhangs that help keep the case on so they should be easier to print. 
• STP included if you want to alter the cutout for the magnet array.

I have been using this version for a few days and so far so good. I printed my latest version on a P1P with a 0.4mm nozzle with no supports except on the mic opening on the camera ring. I would recommend using regular PLA over matte PLA if that is your material of choice because it is more resistant to layer separation when you try to remove the case. 

I am using two different types of tape right now. This tape has better adhesion than the original tape linked below but it settles into gaps over time so I would avoid using this on the hinge side long edge of the front case as the adhesive will seep into the gap of the display and the frame. Also a smidgen thicker than the other one. 

This magnet array fits the cutout already made. I ordered the Silver version.

I printed the model in the images on a Bambu P1P on a Carbon Fiber Effect Plate using Bambu Matte PLA. 0.2mm layers with normal supports painted on the overhangs. If you are confident in your machine you may not need supports but it's a long overhang on the front half. 

For the Camera Cover, Camera Ring, and Magnet Cover I changed the top/bottom surface pattern to Concentric, but this is cosmetic. For the Camera Ring and Camera Cover I toggled on ‘Only one wall on first layer’ but this, too, is cosmetic.

Some notes in no specific order:

The magnet array I used was this one: https://www.amazon.ca/dp/B08Q7XWB85

The array that actually arrived had a pill shaped alignment magnet so that's what I built the model to fit. The array also had a strong adhesive on both sides, so the Magnet Cover stl is basically there to stop the adhesive from sticking to your phone.

This version has a cutout next to the topmost camera lens to allow access to the tiny microphone there. 

I also like having a camera cover so I made one that tension fits into the Camera Ring.

The opening of the front piece was made to go around my screen protector and leave almost no gap. Screen protector I am using is this one: https://www.amazon.ca/dp/B0F8RDXNY5

I had it applied via the included applicator before I measured out the opening for the front piece so theoretically if you use the applicator, it should fit perfectly. If it does not, you will probably have to apply the screen protector by hand after you print and test fit the case.

I am still testing it out but it doesn't feel like it should need any adhesives to stay on, but I am generally fairly cautious with my things so if you are worried about the case falling off, you can use a thin doubled sided tape to keep it on. I have used this for other things with fairly good results and low residue: https://www.amazon.ca/dp/B07N6694MN

I make no claims on drop protection, consider this cosmetic only. 

I may or may not make further revisions.
