Created in Tinkercad (so it's probably not perfect if you look at it in Blender, but prints fine and fits really well)
You will need 27 6x2mm magnets, and some glue (super glue not recommended, unless you're okay with potentially getting that white haze on your unit/pieces).
19 magnets for the pieces, and 8 for the storage compartment which can just about fit the provided USB C cable in.
NOTE: I'm potentially working on a little powerbank that incorporates USB C male that will fit in the compartment and specifically shaped to plug into the wislide without putting stress on the USB C port, no promises. Will link it here when/if done.
The author marked this model as their own original creation.
