Lock-On Device from the movie Runaway (1984)
Another build from the Runaway movie, this time the little computer controlled Lock-On devices, this is a simple 7 hour build, A day of design work and test printing (Currently in paint) but some nice features, and some new test features.
November-16-2020
changed the wheel size so it should be a drop in fit now
changed the display size for a more drop in fit
electronics fit perfectly into the new v2 body (micro switches and dimensions I used are here: https://www.amazon.ca/gp/product/B00O9YOEDC/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1 )
What do I need for this kit?
2-3x Green 5mm LED
1x Red 5mm LED
1 Micro switch
Wiring for lights
Battery (Double A or cr2032)
4 6mm M3 cap hex screws
Design features
simple print
mounts for LED's and on off switch
bolts tie into the prop design and allow access to the electronics
variable front display, the grid can be printed alone from a background plate allowing multi material printing (black background and green grid) or printing in clear and paint blocking to allow back LED colour projecting.
A nice bright top light
Insets for all parts for simple assembly
Assembly:
Print and or paint the wheels black, glue into the insets
Print and or paint the body in white
Print the display using the type of print you want (multi material or clear) and glue to the inner frame
Optional: Mount the switch and glue in place, mount the red LED to the top and the green LEDs to the front posts), wire together to the battery
Glue the back hub into the inset provided
Screw the top down carefully to the body posts (DO NOT OVERTIGHTEN)
Enjoy!
Issues:
the line cuts may not be the best, this was my fist time trying to do this, and it's in tinkercad so it is not designed for it. I think it came out well. My first print had some minor issues with placement, LED's and switch all too close in the same area, and after test printing and testing the front display I found for my LED's I needed 2-3 so I added a holding post for a second and moved the switch back towards the center so it's not an issue
be careful removing the front support on the main body, the top crossover is thin!!!! I did not break mine and once you glue the front display in it fully strengthens it.
Post print:
files the holes for the fit you need to friction fit the LED's (posts were fine, top led needed light filing
remove any elephants foot, widened the insets for this
bolt the top down, fit's nice.
file/sand the edges of the display if it is still tight, my first test needed some sanding, not much but it did need it.

I have tested the blackout paint on the alternate combined display (leaving the grid clear) and it works out excellent.
I have fully tested this print. Photos coming shortly after the paint dries. Any questions please ask.
