IKEA BRAUNIT Battery pack

I own several IKEA roller blinds. These are powered by IKEA Braunit battery packs which need to be charged once every few weeks of usage.I dislike the fact these have to be removed from the blinds (which are positioned quite high up), just to be charged through a micro-usb cable. Rendering the blinds unusable until charging has completed. I designed a dummy enclosure for the Ikea Braunit battery packs. This assembly requires no screws and slides/locks together in 3 pieces. There is room for installing the corresponding blade connector which can be found here: Blade Connector 2.5mm pitch, 4 pin female.https://aliexpress.com/item/4000332107587.html I have added a small voltage regulator in each of my dummy batteries and installed these in my blinds, I no longer have to charge the roller blinds and if warranty is ever needed. I can return the blinds without any permanent modifications made to them. Printed in PETG, but PLA should be fine for these too.
