Assemble the upper part of the projector with the light diffuser, then the central pin, and glue everything together.Â
Place the 2mm magnets in all the holes around the edge using glue.
Pass the LEDs through the model, glue the LEDs around the cylinder and on the opposite side to where the Batman logo will be applied, and glue the lower part of the projector to the complete base.
Â
For the upper part, glue the diffuser as for the lower part and glue the magnets into the appropriate holes.
For the front part, simply slide the disc into the appropriate slot and then insert the Batman logo.
To insert the Alexa Echo Dot 3rd generation, simply remove the top part (which is held in place only by magnets), insert Alexa into the rear slot, and close everything up.
Fit the battery box into the hole and enjoy your new lamp.
Â
Please note:
In the assembled photo, you will notice a little light coming through the projector joint, due to incorrect sizing of the holes for the magnets. This error should no longer be present in the uploaded model, and you should be able to close everything completely and fit the model together perfectly.
Happy printing!
