Hello,
recently there was a big prop & costumes auction of the latest Resident Evil movies so I decided to expand my game prop collection by adding some elements from the movie.
The grenade prop from the fifth movie caught my attention as it has a nice futurist design and offers the chance to include a micro controller for the led bar.
Moreover, Taku Dazai portfolio images offers very detailed references, so doing a precise copy without direct access to the movie prop should be a piece of cake.

For my replica I decided, to make a CAD model and to produce it with 3d Printing, as fabricating it with a CNC mill, like they did, is out of my budget.
Here is my first model version.
I already made a first revision, by comparing my drawing with the reference one I found some errors in the safety level.
Next step was deciding the internal hardware. I decided to use an Arduino Mini with a Li-Po battery. It's my first time in using a controller board to drive a few leds (the prop has a 10 led segment bar) so I am not 100% sure if this design choice is correct. I used the CAD to plan the internal components layout before printing it and I verified that everything can fit inside easily.
I am waiting for the electronic components shipping from China, so my build will be paused for a few weeks.
Last step I will do in the next days is to rework the CAD model an split it in separate parts and add internal supports for the internal components.
I prefer to split 3D prints in separate parts when it is functional to internal parts assembly and for surface polishing.
