Bosch Ixo screwdriver renovation No.2

I bought two non working Bosch Ixo screwdrivers on Ebay.
They are slightly different models.
This is the renovation of the second one

El mas Completo video que he visto y necesitaba ver. Mas que nada porque un dia lo desarmé y lo dejé inacabado. Hoy me falta alguna pieza que ya he odido identificar . Gracias.

This reminds me of the discontinued 7.2volt Dremel Driver. I haven’t been able to find anything like it.

Many of these small power tools look similar inside.
