These are two fan shrouds for the Deltaprintr. Both can be used at the same time. These clip onto the traxxas joints and are designed for standard 40mm fans. I've also included a fun fan shield. The print head shroud was based on this one by Ruyck. To design this, I took a bunch of measurements using a caliper and drew these designs up. Simple as that. Well, I did draw inspiration from Ruyck's design.When assembling this, I suggest that you loosen one of the screws holding the taxxas joints in place. This will allow the shrouds to snap on without breaking a clip. Obviously, don't forget to tighten the screw back up. I used a tap to make sure that the screw holes were sized properly in the shrouds and to make sure the screws had something to screw into. From there I just used some 10mm M3 screws to hold everything in place.
