How difficult would it be to model, and print just the injector frames that attach to the glove from the Arkham Knight Scarecrow, he has four on the hand so it would be a lot easier to do in 3D and duplicate the print. but my 3d skills arent up to the task so what would be the cost of something like this? also another idea would be to build the forearm part with a latch system to get it on or off but that would be at a later date... I have attached a drawing and have found some 12mm glass tubes i could use so would it be easier to design the parts and clip together or as one part as it moves i think looking at the joints
rough model, but something like this? or more where the needles are over the knuckles instead of the hand?
Yes is more the frame that holds the glass cylinder and needles i'm after these will be attached to a leather strap on the hand.
