Mk11 - 3D Printed Durendal

thingiverse

I'm providing minimal support on this, but here are the files for my 3D printed version of Captain Slug's *Durendal* homemade rainbow-catch blaster. This catch transfers the load to screws or other hardware, keeping the printed parts in pure shear or compression for maximum strength even with poor print quality or low infill percentage. The plunger head is a simple design that removes the load from the printed part as much as possible. You will also need US-spec 1-1/4" Schedule 40 PVC pipe, orings, springs, a plunger rod, fender washer, screws, and barrel nuts. Check out the [Nerfhaven thread](http://nerfhaven.com/forums/topic/27889-mk-11-durendal/) or Captain Slug's original [machined version](http://nerfhaven.com/forums/topic/27194-durendal-my-take-on-a-rainbow-catch/) for more information and support. The catch prints as one piece and can be easily adapted to many blaster types, but it requires you to machine or assemble your own plunger rod. I've included the .STEP file for the catch and a drill guide for openness and easy adaptation. The grips and PH are not included as step files because the PH was drawn in SketchUp and the grips are a mess.
