UPDATED FROM v08. Please check out my pbnation thread for info on the change from v08: http://www.pbnation.com/showthread.php?p=97388690#post97388690 This is a work in progress! No guarantees. Disclaimer This is not a simple print project. Don't even think about attempting this as your printer's first prints. You will fail miserably. A successful print requires a well-calibrated printer and thorough knowledge of infill, support, and bridging. Design Blog Please visit my pbnation thread to see more details on the design/thought/test/specs/etchttp://www.pbnation.com/showthread.php?t=4516961 Upper versions The "universal" version takes a universal speedfeed such as the Exalt or GXG speedfeed. The "gxg" version is designed for lower frontal profile and requires modification to a GXG speedfeed, using only the rubber. Fit The Upper and Lower are designed with 0 margin front to back and 0.5mm margin side to side. This means calibration, trimming, and cleanup are required for a good fit. Without a good fit, the shell is more susceptible to damage when hit. Alignment pins Alignment pins are provided for gluing the feedneck to the Lower half. Sizing on the pins depends on printer accuracy and bridging capabilities. Actual size of cavity between the parts is 5mm diameter, 2mm height. Anything ~4-4.5mm diameter and 1-1.5mm height should work. Slice settings This is intended to be printed such that there is at least 4mm worth of solid plastic wall. Each slicer has its own way of defining that, so make sure you know what you're doing. Supports are needed in several areas. Be careful not to get support in the nut holes of the Upper, or be prepared to dig it out with tiny tools. I use S3D, which allows me to define support areas. If you don't have S3D, Meshmixer should work too. Auto-support generation will be tough to clean out the small holes for the 4-40 nuts. Material I printed and tested this design in PLA, to decent success. ABS may be more impact resistant, but I had delaminating issues. Choice is yours. Tools Required 3D printer Philips head screwdriver (for flip tab screws) Precision philips head screwdriver (for 4-40 assembly screws) Sandpaper Precision knife (eg. x-acto) Needle nose pliers Drill (optional) Round file (optional) Materials Required 1 1/4 4-40 pan head screw (x2) 4-40 nut (x2) Gel type CA glue (eg. Gorilla Super Glue Gel, Loctite Super Glue Gel Control, etc.) Craft glue (eg. elmers) Loctite Dye Rotor parts needed (check https://shop.dyepaintball.com) GXG GXG upper requires some cuts in the rubber in order to fit. see pic
