As we have already created the stickers compatible with HP41c, we now need to create an overlay for the HP41c. Still thinking on whether it has to cover the keys (à la HP15c) or not, and if it has to be similar to the originals or from the new transparent silicone.
We need to create a back door for the Spice series. This back door would include the silicone pad too. The jury is still out on whether it has to include the AAA battery holder or not.
We need to create a closing piece for the printers and HP92/97 battery bays. (The two small parts that support the battery closed)
The battery packages for the Classic units - the 3D printing price is so high that we cannot compete with other suppliers. We'll forget this one (we had already some prototypes)
