I somehow got addicted to making phone cases for friends and family since I successfully printed TPU the first time.

  I read Pinterest instead of Printables at first and got ready to shit bricks and throw tables. What am I gonna do with all these bricks and tables!?

Word of warning, 3d printed cases are a bad idea. The plastics don’t actually absorb the impact like a real case would, and so they break often and don’t actually absorb the impact and protect your phone. Every time I’ve used one I’ve ended up with damage.

  Did you use TPU for the prints? If you used PLA, that really was a bad idea. With TPU my drop tests (not on purpose) were successful and the phone without damage everytime (so far)

    I used nylon carbon fiber.

  It depends how thick and soft the tpu is. If you have a thick enough and soft enough case, it will absorb an impact. Just like silicone cases do. And they are also solid.

This is how it starts. Next thing you’ll know you’ll be optimizing phone shapes, learning physics about drop protections, and soon starting your own case company.

  You might be right, I looked up a lot how Spigen gets their cases durable recently in order to create a really rugged version :D

  What phone do you have?

  - koolkiwi@lemmy.world ⁨1⁩ ⁨year⁩ ago
    Xiaomi Poco X3 NFC. Doubt there’s enough people running around with this this that it’s worth putting time into making a case for it :D

BTW… In the process of designing these there were made a few prototypes. They all are not perfect, but if someone (from Germany) wants one, here is my stock :D If you have questions on a specific one just ask. I would give them away for shipping+packaging cost.

iPhone 13 (regular):

blue Mama Version

big MagSafe Cutout Bumper

iPhone 13 Mini:

slim hex back yellow

thicker round hex cutout transparent

rugged small hex back yellow with grip pattern

iPod Classic 5G:

neon green case with hex back

This is amazing! Well, great excuse to buy more TPU :)

  Oh you are so right :D I bought 3 rolls last week… Using this one for my cases btw:
  
  SUNLU TPU Filament, 1KG Flexibles 95A TPU 3D Drucker Filament 1.75mm Maßgenauigkeit +/- 0.03 mm, Hohe Liquidität und Elastizität, 1KG（2.2Lbs) Spule, TPU Filament für FDM 3D Drucker,TPU Gelb amzn.eu/d/872AVs6

How soft/bendable is it compared to silicon cases?

source
- moody@lemmings.world ⁨1⁩ ⁨year⁩ ago
  It’s flexible enough to get a phone into it, but it still feels pretty stiff, depending on thickness and infill settings. It’s flexible but not really stretchy.
  
  source
  - redcalcium@lemmy.institute ⁨1⁩ ⁨year⁩ ago
    As long as it’s flexible enough, it’s probably enough to protect the phone when falling on a hard surface. Just another reason to get a 3d printer. I’m having a hard time finding cases that I want and never thought it’s possible to make one using 3d printer.

I’ve had pretty good results with TPU as well. However I recently found some filament called soft PLA which has been similar structural properties to TPU, but seems a little more forgiving with print settings.

  Interesting, could you share a link please?

Enjoying the paracord, I might give this a go on my current case. How does the connection look like?

How much more difficult is it to print TPU compared to PLA?

source
- Gorroth@lemmy.world ⁨1⁩ ⁨year⁩ ago
  I would say that depends on you, your printer and the used filament.
  
  On my Voxelab Aquila out of the box with official slicing Software I could print PLA without issues, but with TPU it would have been impossible. Now I use Astroprint.com for slicing where I control print settings in more detail than it would be possible with Voxelab’s slicer. So that was the first step to take. Also I upgraded my printer to DirectDrive and DualGearExtruder. I then needed a new fan shroud, because the one I used before didn’t fit anymore. Then I had to learn about e-steps, because somehow I went into Unterextrusion (after switching to the dualgear Extruder you need to get the e-steps set new depending on the new extrudergear thickness. Luckily it was mentioned on the package it came in). Then the TPU started wrapping around the extruder gears. Turns out I printed too fast and so on…
  
  Long story short. Depending on your printer, I would suggest at least switching to DirectDrive if your printer doesn’t have it. Also print very slowly, like 20mm/s slowly.

    ah this is the professional CAD tool from autodesk. I only used the minimalistic web version of Tinker CAD, probaly enough to do small customizations on cases

moody@lemmings.world ⁨1⁩ ⁨year⁩ ago
Have you tried printing with infill but no top or bottom layer? You can get a pretty nice look with stuff like exposed gyroid infill.

source
- Gorroth@lemmy.world ⁨1⁩ ⁨year⁩ ago
  I did this for a few inserts for like glasses holders and stuff, but not yet for smartphone cases. Wouldn’t it then also expose the top of the edges? Also I think it would probably collect very fast, very much dirt in my pockets :D
  
  source
  - moody@lemmings.world ⁨1⁩ ⁨year⁩ ago
    It depends how thick the top edge is. You can also enable ironing to smooth out the top and make it less visible.
    
    I don’t think it’s much worse than your examples with holes in them.

Magrath@lemmy.ca ⁨1⁩ ⁨year⁩ ago
What orientation do you print these in? Looks like you’d need supports and I’ve had trouble getting nice finishes on the side that needs the supports. I’ve only printed with PLA though.

source
- Gorroth@lemmy.world ⁨1⁩ ⁨year⁩ ago
  I printed most of them laying on the back to get this nice PEI printbed finish. The only one I printed upside down is the LEGO one, because I was afraid the back would look ugly if supports where on it. Of course you could print all of them facing the back up, so the „ugly“ supported sides are inside. You obviously will need more filament that way because of the supports, but it should work just fine.
  
  BUT…
  
  I highly recommend printing these in TPU, not PLA. I don’t know if you will even be able to get your phone in these, as they get a bit around the phone and PLA is not really flexible. And even if you get it in, it will possibly brake fast and not protect your phone they way it should.
  
  source
  - Magrath@lemmy.ca ⁨1⁩ ⁨year⁩ ago
    Oh of course I’d print them in TPU. I was just saying that because I have no experience with printing it and if the ugly side is as ugly with TPU. That’s my only concern with printing a phone case. I’m pretty new to 3d printing so I only just learned some the limitations and the ugly side of things lol.
