Xiaomi MiJia M365 - custom battery for extended battery

Custom battery cover for my battery design: https://www.thingiverse.com/thing:4538027
I printed it using ABS in three parts and weld together using ABS glue, but any (non flexible) filament should be fine.
Aluminium bottom battery cover and battery cover seal both bought on Aliexpress (just search "m365 bottom cover" or "m365 cover seal", there's plenty of these).
Screws used:
12x M3 20mm
2x M3 10mm (7mm will be fine too)
3x M3 7mm
