This model consists of replacement latches for the LEGO EV3 battery pack, designed to replace broken ones. It is a single component featuring two latches; to install it, you must modify the battery housing by removing some plastic in the area where the latches are located (the part is 70 mm long). The photo shows what the battery looks like with the plastic removed. I have included three holes for small plastic-threading screws, though these are optional—the part should stay in place even without them (at least when the battery is inserted into the controller).
A potential drawback is that you may need to modify some of your robot builds, as the battery becomes slightly thicker at the site of the replacement latches.
Print the model vertically so that the latches run along the layers.
Layer thickness does not make a significant difference.
Use PETG material for printing.
Use supports and a brim when printing.
