Thanks for pointing out the older files. Have removed them. For now, the initial post has the latest files.
The initial post also has two sets of similar links in two places as I explained in my previous post.
Please specify which is the correct one, and/or remove the incorrect ones.
@LittleTurtle Yes, the design of the case makes it a bad choice for the particular TPU (40D) my friend used - the walls are too thin and as a result, the walls do not hold the phone reliably.
I spoke with a commercial 3D printing shop and learned there are more rigid materials, such as semi-flex (they gave an example of TPU Rosa-FLEX 96A), but still recommended a redesign to make the walls a bit thicker. They looked at the STL I provided and said it was a problematic design, they feared the customer satisfaction would be less than optimal when printed (or they would have to re-run the process for the result to be acceptable), so they concluded with a denial of service. This was a clear sign of a problem with this case (the design of it).
Not to mention their policy is to charge a minimum of (an equivalent of) ÂŁ40 (excluding taxes - 23% VAT in my case!) so this vendor would be a no-go anyway.
Question:
can I get a CAD drawing of the M2 enclosure? My idea is to import it to my CAD software and try to design a case for M2. Would that be possible?
Should I speak with the helpdesk to get the answer?
Let me pass on the query to the /e/OS design team. Will get back with the response.
Great, Manoj. Thanks!
Midland 3D company suggested trying 95A instead of the more difficult material 85A. Their price is lower than the company you mentioned but I have no idea about export costs to EU.
I am afraid I have little knowledge of 3D so just searching online here are two links that maybe helpful:
How to Convert STL to DWG (AutoCAD): https://all3dp.com/2/stl-to-dwg-how-to-convert-stl-files-to-dwg-autocad/
Free Online CAD File Converter for DXF, IGES, STEP and STL: https://convert.emachineshop.com/
Donât worry - it is not the only or last option I have. I will try another printing shop - we will see what happens.
Thank you much @LittleTurtle for the links. What I actually need is not something can use to convert existing designs (meshes) of the protective case, but to know precisely all the dimensions of the phoneâs enclosure to be able to work with those in an effort to design my own case on some CAD platform. It is the proper way of approaching the subject compared to manual measurements of the physical phone (which is prone to errors as one can see with the camera hole in the back of the case - design #1, major issue).
The application MeshLab has a measuring tool. Although it is not very accurate because it depends on where you put your cursor on the diagram.
The bezel on âM2 case protected openingâ seems short (not enough depth) by just looking at the diagram. So I measured the bezel in the stl document in MeshLab with the measuring tool, and it measured roughly 1.7 which means if you put the phone on a level surface the lenses will still touch the surface. Therefore it seems pointless to waste money and time getting it printed via 3D printing companies.
Midlands 3D replied back: âWe can try this in TPU 95A, however, we wonât know how flexible this will be and if the buttons will work as well as you are hoping. Regarding increasing the bezel, we are unable to edit a 3d modelâŚâ
The manufacture of cases only takes two weeks and after many months we are still waiting and being presented with excusesâŚ
Yes, this is a very disappointing situation.
Thank you, @LittleTurtle, for the information on the measuring tool in MeshLab.
When I asked for the CAD drawing of the phone - I meant the reference for a [yet another] case design (which I could attempt unless they delivered what was promised earlier) rather than something that would help me verify any existing case design by comparing it to the CAD drawing of the phone enclosure.
It is sad to read the camera bezel is not thick enough. Hard to believe, really.
Those excuses you mention at the end - as @SSD pointed some time ago:
Well, as @Manoj recently clarified - the design for a 3D printout is a separate effort (by the team @ /e/OS while the factory which was supposed to manufacture the case would also be responsible for their case design. If so, I would expect a significantly longer period until the batch is done and shipped to those who await delivery.
Yes, I feel the same. Something isnât exactly right here.
When you look around and start noticing more strange issues surrounding Murena 2 (like the one with the camera focus not working as expected) the overall picture gets even worse.
My feeling is there are only a few people in Europe (France?) making some general decisions, like, for example, how to allocate funds and where the design and production activities should be outsourced. Then, they deal with those who do the work and donât deliver on time, or deliver stuff with bugs. Not a good situation to be in, I imagine.
The vendor who was manufacturing the phones did not supply the back cover protectors. There were also complaints about the camera quality.
We took up the back cover issue with the vendor, who has till date not given us firm answers.
As such, we are moving ahead and will be getting the back covers 3D printed from a different vendor. Will share the dates when we will have the back covers ready for distribution to users.
Based on the learning from this, we are also looking at different manufacturers for future models.
OK, but hold on there, @Manoj! When you say:
you donât mean the camera focus issue, I hope. This has to be solved in the software
(if it is the software bug) or ehmm⌠a recall of the phone if the camera module has a hardware fault, right?
There is an open issue around this in Gitlab. Once the developers pinpoint the reason for the camera related issues we will share the resolution.
I know it is discussed on Gitlab. I have been monitoring the situation there and seen some interesting tag re-hasing over the past 48 hours, or so. Hope, it does NOT mean a hardware bug!
OK, got the announcement in the e-mail (via KickStarter). If this is the situation, I need a confirmation of which particular design (blender project as I understand it) is being processed further and which material is going to be used for the production of these protectors. We already know the materials that are a definite no-go, so this request is for verification purposes.
3D is better than nothing I suppose, hope you will improve on the files linked on this page. The bezel is not thick enough on the stl file - and the button slots donât seem right on the blend file - (havenât checked its bezel).
blender is an unfinished project of the 3D case (âfor experts onlyâ as alluded to by @Manoj ). STL-s are pseudo-code (lets say) for further post-processing in a slicer, which, in turn, produces the âmachine codeâ (G-code) for a given model of a 3D printer. Hope this helps.
I hope the logo and slogan on the back (essential! after all this is Murena, built with Privacy-In-Mind!) shall be proudly presented. Problem is: those objects in blender are too small and even a little nozzle (caliber 0.2 mm) cannot reproduce the fine lines correctly. Those two objects have to be enlarged a bit and the designers should work with the machinists (3D printing specialists) to find the proper balance between size and readability. Similar note applies to the button holes. The designers shall cooperate with the ergonomists to get the proper shape of the holes (conical, I think) so there is no obstruction and the biometric scanner can be used with ease. Mechanical engineers should have a word when it comes to the walls with many holes in them - as they tend to lose their stiffness when the parts of material (especially TPU) between the holes are to tiny / narrow. This is especially important near the top edges. It seems the design is not trivial at all (to make the case decent for the users).
(CAD drawing of Murenaâs enclosure)
it has been nearly two weeks. What is the status?
There are no updates. We are awaiting receipt of the 3D screen covers from the new vendor, which should start coming in by mid of may.
When you, @Manoj, say the covers should start coming in by mid of May - you mean from the vendor to Murena, correct? If so, sadly, this doesnât match Murenaâs own announcement on Kickstarter which they posted on Apr 25 2024 at 9:15 AM:
As of yesterday, weâve switched gears to Plan B: weâve ordered 3D-printed Murena 2 cases, that are planned to ship out from the factory by May 6th.
Unless the vendor is so far away it takes more than a week to get the cases to Murena (located in France, I presume?).
Also, when you say âno updateâ (on the CAD drawing of the M2 enclosure - not to be confused with the protective case) - does it mean Murena would not share that with us? If yes - why? I really would like to get it for my own future projects. Thanks.
