I was asked by a friend if I could make a print of a Vortex Manipulator the same as the one Dr Who? and Torchwood have so I found some pitchers and copped them and made this I did about 11 copes improved it with each print I used PLA and ABS with a 0.25 and a 0.35 Tip with supports the size of it is in the black pitcher as close as I could guess The 1/4 it is round fins/vent holes is a lot of long holes air will go through they start to print from off the bed it was easier to slice this way the fins can be routed off from the bottom underneath with a hand router but not to much as it can damage the fins at the top there is room for a circuit board if you use SMD LED although I have not done this I would use it as the base The buttons after they are cleaned do go through the holes you can put a small spring with contacts so they can be used or they can be glued as a fixed button well Good Luck Let me know what it comes out like Cheers (Piper) Mikele Amorico
