Quoted from Geteos:Looks pretty good. What size LED are you using in the holders?
3mm flickering amber LEDs. I bought a bag of them online, but you can also scavenge 5mm flickering LEDs (and 3V lithium batteries!) from those dollar store LED tea lights.
While printing the final version of the gate parts today, I wired in this big guy. The Jeep is a Matchbox JP car I modified with LED headlights. I'll be replacing that clear shield the Jeep is sitting on there with a sculpted terrain piece that gives the Jeep a road to drive on. I'll use the flasher socket underneath there to power the headlights and add a spotlight on the T-rex.
