Thanks for downloading!
We'd love to hear from you if the print was successful.

This is a work in progress! No guarantees.
This is not a simple print project. Do not attempt this as your printer's first prints. You will fail. A successful print requires a well calibrated printer and thorough knowledge of infill, support, and bridging.
Please visit my pbnation thread to see more details on the design/thought/test/specs/etc
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.
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 is required for a good fit. Without a good fit, the shell is more susceptible to damage when hit.
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.
This is intended to be printed such that there is at least 4mm worth of solid plastic wall. Each slicer has it's 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.
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.
- 3D printer
- Philips head screwdriver (for flip tab screws)
- Precision philips head screwdriver (for 4-40 assembly screws)
- Precision knife (eg. x-acto)
- Needle nose pliers
- Drill (optional)
- Round file (optional)
- 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)
- Dye Rotor parts needed
- (check https://shop.dyepaintball.com/collections/replacement-loader-parts/)
- Anti Jam Pull Tab
- x2 Locking clip with screw and oring (red clip that holds everything together)
- Bottom Tray (black cup)
- Bottom Tray Gears (red main gear with white small gears)
- Center Arm (red spinny thing)
- Top Eight Ball (black octopus)
- Main motor drive and battery tray
- For low profile _sf version:
- 1/2 4-40 pan head screw (x3)
- 4-40 nut (x3)
- Print parts, remove supports
- Poke out the print bridges blocking the 4-40 screw holes using a screw or precision screwdriver. (2 holes in Lower, 2 (or 5) holes in Upper)
- Test fit between the Lower and Upper, noting sources of friction. Trim, sand, cut out sources of friction.
- Test fit of Button and Antijam, noting sources of friction. Trim, sand, file sources of friction.
- Test fit of Feedneck, Alignment pins and Lower half. Trim excess.
- Slightly scuff bottom of Lower half and top of Feedneck (this allows for better glue adhesion)
- Using alignment pins as guides, glue the Feedneck to Lower half. Apply pressure as needed for curing.
- Disassemble Rotor. Be careful not to lose the button if you want to use the stock rotor again. Antijam will need needlenose pliers.
- Carefully screw the Locking Clips into the Lower half. These screws will tap into plastic, so do not overtorque. The Locking Clips should have similar friction/feel to stock Rotor when assembled correctly. Leave in "open" position.
- Place Antijam and Button in place.
- Place Motor Drive and Battery Tray in place with a back then front rocking motion to lightly snap the assembly in place. Verify Button and Antijam function properly.
- Drop in Bottom Tray Gears.
- Drop in Bottom Tray.
- Drop in Center Arm and Eight Ball.
- Move Locking Clip to "locked" position and verify it properly holds motor drive and eight ball assembly in place without a lot of friction.
- Retest Lower and Upper half fit. Upper should just barely clear batteries. Trim as necessary.
- Drop a small amount of elmers glue in nut holes of Upper. Insert nuts and screw in 4-40 screws to hold them in place while the glue dries.
- Reassemble Lower and Upper, secure with 1 1/4 4-40 screws using loctite.
- Attach speedfeed.
- Play paintball.
GXG upper requires some cuts in the rubber in order to fit. see pic.
