With the #Pinephone's current short battery life, and no major improvement in sight (that I know of), it seems like a good idea to purchase a backup battery. Having to take out the whole back cover is a hassle though.
I just found that @PINE64 supplies the CAD file for the back cover in STEP format! I would like to have a cover with an integrated door, think TV remote.
But is there any current 3D printer that can print such fine details?!? Mine circa-2013 sure can't.
Bit of info that will be interesting only to CAD jocks: the STEP file was generated in Pro/Engineer. Not sure what version, it reads "PRO/ENGINEER BY PARAMETRIC TECHNOLOGY CORPORATION, 2010280".
Did you know? A STEP file is a plain text file. 🤓
What I meant is, I strongly doubt that any 3D printer can actually print to the level of required detail. At work I occasionally have 3D prints done by commercial machines. Lately in SLS (selective laser sintering) which is much more refined than FFF/FDM. Even in SLS I don't know if those tiny tabs can be done accurately.
Yes, I was thinking of designing a thicker bottom cover to allow for a door, but the case still has to snap to the contour frame. So the snapping tabs on the sides need to keep their current size and shape.
I made a demo quote with their default part, a small enclosure 75 × 38 × 58 mm, printed in SLS. It would be $24, but 3D Hubs has a $100 minimum charge. Ouch! I'll have a look at other services. I don't remember Shapeways having a minimum charge.
@normandc I didn't realize they'd pivoted to another model, I thought it was using independents like you mentioned:( $100 minimum, that sucks!
I had a look at the blog section. There's a board of directors and everything. Fully business mode now.
I remembered a local 3D printer who was on 3D Hubs years back. His website is still online, he went commercial. He does SLS, I may inquire for a quote.
Ah well, first I need to find the motivation. I do design work for a living, and at the end of a work day, well, I want to do something else... It's the main reason (among others) why I left the FreeCAD community.
And about those small possibly difficult to print tabs, I realized that instead, I could screw the printed back cover, using the existing screws holding the internal assembly. Maybe get longer screws if needed.
And while we're talking, also making the SIM & SD card slots accessible as well would be a nice bonus!
Another possibility: get another #Pinephone back cover (only $5), cut out an opening for battery and card slot, glue the printed back cover over it as an outer shell.
