Description

Offered for sale are the 3d print-ready files for a Mk17 Gryphon-Volt - 3d printed homemade blaster! Files are designed to be easy to print on your 3d printer with a bed size no more than 200mm^3 (Ender 3, Prussa I3, etc). Smaller beds will likely work, feel free to contact for part sizes.



*Let me also be clear: The Gryphon blaster, upon which this kit adds, was originally designed by Flygonial and is available at the link below licensed Public Domain. I have included my altered Gryphon parts for simplicity and ease in visualizing and assembling the blaster, but I do not lay claim to their design or intend to charge for them. I have based the price of the files on the estimated sale cost of the kit alone.*

For anyone wishing to acquire the files for personal use, once downloaded you may make as many as you want for yourself and friends who aren't paying you with more than filament.



For commercial sellers and commissions, (1) one purchase will cover the design fee for (1) one sale. Outside of this exception, the files are provided to you for personal use only.



To complete the project, you will need:



- A halfdart mag or hasbro-brand full mag & darts



- The parts from this listing printed on your 3d Printer (I print in PLA at 0.2mm layer height, 20% infill, 1.2-2.4mm walls/3-6 shells. You need everything in the STLs.zip, however you may wish to trade out the FWC and FWC_Cover pieces for different motor spacing. Included in the main files is a 40mm cage and cover. Included in the Extras zip is a 43.5mm cage and cover; additional crushes are possible and will be added upon request). The files have been sorted by color shown in the images, use whatever colors you desire in whatever combinations look good to you but try to keep the muzzle orange if you'll be using the blaster in public. I checked the pieces - all should fit on a printer as small as 7"/175mm^3. V4 files are new with lots of tweaks inside and out for easier/more forgiving printing, assembly, and operation - they haven't been tested but V1-3 worked so I expect V4 to work as well. Major changes are to the internals (gears have plates added for better print quality and stability) and the foregrip (hole added for a through pin/bolt).



- A rubber band or elastic/shock cord (for the stock catch, mag catch and trigger; alternatively the gryphon's sprung trigger & mag catch should also work)



- A handful of #4x1/2", M2.6x12mm, or M2.5x12mm *coarse thread* screws. Sheet metal screws work great. You'll also need a 3/4" (20mm) screw for the mag release.



- 130, "132", or 180-size motors for hobby Nerf blasters.



- Motor mounting screws



- Standard size flywheels for hobby Nerf blasters.



- 18ga or 16ga stranded wire; silicone insulated is nicer to work with



- Heatshrink



- An "Omron" style button or short lever microswitch; clones are fine. You can clip the roller or faux-roller off a roller switch and it should work as well.



- A connector to fit your battery (Generally an XT60)



- A battery capable of supplying your motor's current demands and matching their voltage. Check https://suild.com/tools for battery vs. motor compatibility.



- Short pieces of 1/2" (OD 0.84"/21.5mm) and 3/4" (OD 1.050"/26mm) PVC. If redesign is required for local materials, please reach out to me with dimensions of locally available options and I'll see what can be done. The 1/2" PVC is used in the stock and could be substantially undersized and work fine. The 3/4" is used in the barrel and needs as wide an ID as possible to avoid contacting darts leaving the blaster.



This is a rough guide to assembling the parts, please use your own judgement and experience and work safely:



Build the flywheel cage - install the motors to the cage with the motor mounting screws, ensure they are held tightly and spin freely. Install the wheels on the motors, again making sure they spin freely and are level and square. Wire the cage up with "+" to one side, "-" to the other, leaving at least 18" (45cm) of tail wire. Check free operation and correct direction of rotation with an AA, C, D, or 9v battery, make adjustments if required. Screw the flywheel cage cover onto the cage.



Attach the Magwell to the flywheel cage. Install the magwell catch.



Build the grip - install the flywheel trigger, omron-style microswitch (verifying operation), trigger, elastic, gear, and magwell joint. Use a piece of 1.75mm filament as a pivot for the gear. Add the pusher on top and install the three mech housing parts. Verify clean operation of the pusher.



Attach the grip to the magwell, verify pusher operation. Install the wire covers in the FWC Riser and install over the assembled flywheel cage, feed the "-" wire through the riser and into the mech housing and grip. Run a loose wire down the same route to the switch and attach one to the "com" leg and one to the "NO" leg. Add the grip cover & grip panels.



Attach the rear riser, top pic, barrel shroud, front, front pic, and 3/4" PVC into the FWC Riser with the two side pic rails. Attach the magwell angle to the motor cover, attach the motor cover, wire the "+" and "-" wires to the appropriate terminals of the battery connector. Slide the foregrip on from the front and screw on - the foregrip will serve as the battery bay.



Assemble the stock pieces; using a piece of elastic tied through the hole in the latch and the pivot piece and the 1/2" PVC. Put adapter block into the rear riser, the stock reinforce into the back of the rear riser and slide the rear riser over the back of the mech housing and onto the top pic. Attach the stock.



Cut the 3/4" PVC to desired length, add the muzzle, and marvel at your completed blaster!
