I’ve been buying these insanely cheap Bluetooth LED speaker / microphone systems for their hardware to put into my 3D Prints. I’m trying to get the things that I design / modify to be useful

To the finishing and painting crew, what is your favourite type of plastic filler?

Wanting to try a few different options, at the moment I’ve been using automotive filler (cures way too fast for my liking, making it hard to spread around) and i’m about to try some Humbrol plastic filler for models..Just wanted to see what the rest of you use, cheers http://ift.tt/2s3tAek
