Hello, I am also having this issue. I have two pocket reforms (one purple, one black) and the RK3588 upgrade:
- does not fit in the purple unit without extremely concerning bulging in the middle of the lid above the SOM; I could barely tighten the screws and did not proceed with the upgrade
- does barely fit in the black unit with somewhat concerning bulging in the middle of the lid above the SOM; I was able to partially tighten the screws by omitting the thermal pad. I left the RK3588 module inside the black unit and I’m now using it as a desktop — it is a fantastic upgrade!
I do not think this is my error inserting the module, I had previously upgraded the purple unit to A311D and the lid fits above that module perfectly flush with the case. I tried re-seating the RK3588 modules numerous times, with the same outcome each time in both units.
Is there anything I should try short of making a custom lid? Open to any suggestions, is it possible that by “tearing down” the units I could get to the bottom of the variation between my two units? Or is this roughly what should be expected from the tolerances inherent in manufacturing Pocket Reform cases?
If a new lid is necessary I’ll just try to make one. @Khaaan , could you share your new Freecad file in progress…? I am also looking for module dimensions in the Reform repositories with no luck — unfortunately I have no experience whatsoever with CNC milling or CAD.
Is this thread the “canonical source” for your (gorgeous raw aluminum) custom case? Do you expect a one-off order from PCBWay or JLCCNC to make a custom lid successfully for less than $50 per lid?
Anyway, here’s a photo of the lid barely fitting on my black unit with RK3588 module installed. This is the v2 lid directly from MNT, which I got with my RK3588 modules. Any suggestions/help appreciated!
