This is one of my older planes - its obsolete and doesn't fly that well compared to my newer designs!

check out my other models here on thingiverse and more models and books I wrote on 3D Design and 3D Printing here at threedsy.com


For a better flying glider, check out the Stratos :



The new wings start with 'Spritejet' instead of 'Deltajet' and require a .15 layer height. If you wish to stick to the .30 layer height, use the 'Deltajet' wing.

Your printer will need to be capable of printing smooth 1 and 2 layer prints. The wingspan is 150mm, and the wing must be printed on the x or y axis.

Layer height matters, as does fill ratio. Decreasing the fill ratio for the fuselage will shift the CG aft, reducing stability. I am using .3177 - you will want to be as close to this as possible.

If thinner layers are desired, use a factor of .3mm (or .32mm) . The first layer is .6 ratio x .3177mm on my printer. My nozzle is .35mm, but a .5 should work fine. If your nozzle is smaller than .33, adjust the perimeters accordingly.

The wing is printed with an axis - orthogonal fill orientation to minimize warping and maximize durability. The first layer should run lengthwise, the second spanwise.

The wing must be very flat. Use care when removing it from the bed. Peel it up from the front, being careful not to disturb the spanwise symmetry. If the wings are not perfectly symetrical when viewed from the front of the aircraft, adjustments will be required.

Glue the fuselage halves together with the wing in place and seated forward. Run a bead along the outer edge and press together. The wing does not need to be glued to the fuselage. Get the alignment correct before gluing the fuselage halves.

Known working instructions:

Print the wings using ABS. .30 layer height (or close) , 3 perimeters, and 2 solid layers, 35% line fill. Use a fill orientation of 0 degrees to the axis of the part, so that the first layer runs forward and aft.

Print the fuselage halves using ABS. .30 layer height (or close) , 2 perimeters, and 2 solid layers, 70% line fill. Use a fill orientation of 45 degrees to the axis of the part.

Print the launcher with 3 perimeters (2 for .5 nozzle), 2 solid layers, and .35 line fill. Two perimeters are not enough, and will break. Scale the part to your preference - it is not layer critical.

Assemble the two halves onto the wing from each side, with the smooth side up. Use super glue to stick the halves together when you are satisfied that the airplane is symmetrical and that the wings are perpendicular to the fuselage. Put on a nice strong rubber band, and fly!

The control surfaces can be cut free to change the flight charateristics, and a small hole is provided to accomodate wrapping copper wire or solder for weight.

Other materials and layer heights may work as well, please post your results!

Update :

Prints fine with PLA. Extra care needed during removal. Nominally heavier. Works but is less durable and harder to glue - not recommended if you can use ABS.

Added the V2 launcher - prints cleaner, less plastic.

Removed plate - retired old fuselage design.


Added the model 2 fuselage - same print instructions, more durable, better aerodynamics out of the box. (less up elevator built in) This fuselage will work with all wings in the spritejet and deltajet series.

Added 2 new wings - these are designed for a .15x layer height. Print them with the same orientations, only use a .15 layer. The Floater gives enhanced performance with more wing area for the same weight, while the glider wing gives maximum gliding performance, but is slower.

Have fun!!

I tried 3 of your gliders and they all weren't woring. I read the readme and did everything, but it just didn't work. Are you testing the glides (the airflow) with a software? And when yes, what do you use? Maybe you should try to make wings that are working like the real planewings.

Hi, the sprite jet is an early design that is tricky to adjust, and even when properly adjusted does not fly as well as many of my newer designs.

If you read the comments below, you will see that other people have had good results with this design, but I still reccomend you use one of my newer, more forgiving designs... They are in all respects better gliders.

I'd try the stratos and monarch gliders first, they are very forgiving to adjust and fly much farther anyway.

I have some links to YouTube video of the stratos gliders on one of my designs here, not sure which one.

Thank you for the answere! I tried the moon flyer, the stratos glider and this one. You are right, i saw them fly in the videos. But i don't know why they don't when i try them out. The most gliders just crash into the ground after 2 meters. Or they turn around like a boomerang. But i have to say i tried the nost time without a rubber Band. I have a challenge with a firend; he said he could fly a longer distance with a paper plane. I would be interested in the software you use! Please tell me. P.S.: I am printing with an Ultimaker 2 (i tried PLA and ABS).

Fuselage parts can be welded instead of glued. I used nail heated over flame, but soldering iron seems to be better, or even plastic-welding equipment. Thanks for the design!

Fantastic! I printed at 0.9 scale to fit the Replicator, seems to have been a good fit.

Then I tuned it and, in an amazing looping flight, launched it atop a building! Oops. Here's a brief article about the event: http://www.makersite.com/blog/2012/8/22/easy-come-easy-go-sprite-jet-printhttp://www.makersite.com/blog/...

I'll reprint and post better pics. Thanks for the model, it's great.

I scaled it down to get 0.25mm layers (x0.835), printed with the std Replicator profile
amp; Printomatic. Thanks for the model, I love it!!
