April 2025 Release: Boingy The Rabbit

Once upon a time in a lush green meadow, there lived a cheerful rabbit named Boingy. Boingy was no ordinary rabbit. He was known throughout the meadow for his incredible bouncing abilities. With his long ears flapping in the wind and his fluffy white tail bobbing behind him, Boingy was a joy to watch as he hopped around, spreading happiness and laughter among his friends.

Boingy Is made up of 5 separate files: Front legs, Back Legs, Body, Head and Springs. It's easily printed and assembled in less than one minute. I have added a .3mf files as well to save you from coloring the body and head as well. Boingy's tail is articulated and features suspension legs. Includes two versions of the head. One with printed eyes and the other that incorporates 14mm glass cabochan inserts. Glass eye inserts only work at current scale.

8 files or currently included
•Head with eye inserts single color .stl
•Head with eye Inserts colored .3mf
•Head without eye inserts single color .stl
•Head without eye inserts colored .3mf
•Colored body .3mf
•Body single color .stl
•Leg springs print petg
•Front and rear feet

3D Print Settings:

•Use 15% to 20% Infill
•Prints in place
•No supports needed
•The springs themselves have to be printed with Petg to retain any type of springiness. Pla is too brittle and will break.

Arr mateys, prepare to unleash a truly legendary 3D printable pirate cannon! This model is crafted for maximum scale and plunderin' fun, with barrel parts that thread together for maximum build volume. Whether ye print it at full size or scale it down to 50%, the threads hold true, ready for action! A pro tip fer assembly: twist each threaded part back an’ forth slowly to break in the threads, ensuring a snug, shipshape fit, you don't be wanting and bits and bobs in barrel causing mis fires. We have plenty o' pirates with hooks.

This isn’t yer average cannon—it's split fer easy multi-color printing, letting ye add rich details straight from the print bed. With interactive features like a 3D printable spring, pull plug fer firin', an’ a ram rod to load the shot, this cannon’s ready to dominate yer next adventure! And fer an extra touch, the rear wheels have removable pins, lettin' ye raise the barrel to aim high—perfect fer those dramatic, last resort, mast-targeting shot.

Threaded Barrel Assembly: Four-part barrel features threads for an easy, tight assembly. Even at 50% scale, these threads are ready to perform.
Large Scale & Color-Ready: Designed to fill a 250mm cubed build volume, with a hefty 2.5-inch cannonball at full size, and parts split for multi-color printing without a multi-color printer. You'll be wantin' 10 feet of 1/2 inch rope to tie 'er down.

Hidden Supports: Though supports are required on some parts, any surfaces needing them are cleverly hidden when oriented correctly on the bed.

Interactive Firing Mechanism: Features a 3D printable spring, ram rod, and pull plug that you can tie a pull string to for a realistic loading and firing experience.
(Firing experience and tension may vary based on the materials and wall thickness you use)

You can increase the firing power with additional walls to the spring, but keep in mind, more power means hard to pull the pin.

Adjustable Rear Wheels: Removable pins allow ye to tilt the cannon just like the legendary shots aimed for the mast!

Equip yer fleet with this massive, pirate cannon model, and bring the thrill of the high seas to yer 3D printer. Print, assemble, an’ prepare fer battle, ye bold buccaneers!

The c9kinetic Projector is a unique and compact toy that demonstrates the principles of compliant spring designs. It is capable of launching small plastic projectiles using the elastic energy stored in a specially designed compliant spring. The mechanism is powered by a 1-piece, 2-stage, 2-layer spring, which allows for a compact and less flat design inspired by the well-known BYU "One-Piece Compliant Mechanism Disk Launcher."

For more on compliant mechanisms, check out BYU's resources.
https://compliantmechanisms.byu.edu/maker-resources

This toy is entirely 3D printed and uses a snap-together assembly—no hardware, fasteners, or adhesives are needed.

The spring is "charged" (compressed) by rotating the barrel 90 degrees, allowing you to load a small projectile into the back of the barrel. The barrel stays in place thanks to a compliant locking system on top of the c9kinetic, which can be released by gently pulling back on the lock with your thumb. When the barrel is rotated back down, the system automatically re-locks.

Additionally, the grip is foldable, allowing you to reduce the overall size of the c9kinetic Projector for convenient storage.

**Print Settings**

I recommend printing the spring in PETG with 100% infill, the other parts can all be PLA with 4 walls, 40% infill.  The projectiles will benefit slightly from a 100% infill as well.

For the best results, I suggest the following:
Material = PLA / PETG
Nozzle = 0.4mm
Layer Height = 0.2mm
Line Width = 0.4mm
Wall Count = 4 (1.6mm)
Top and Bottom Layer Count = 5
Detect Thin Walls = ON
Wall Generator = Arachne
Ironing = OFF (not needed)
Support = All required support is designed into this product  
Material and Infill: 
301 Sping: PETG, 100% infill
Projectiles: PLA, 100% infill
All other parts: PLA, 40% infill, cubic

Print Orientation:  As per STL/3MF files

**Revisions and Updates**

I occasionally update and revise my designs. When I do, I’ll document the changes here. Check back periodically for the latest revision notes or if you’re experiencing any issues with a model.

2025-03-14 15:26 PST; the original files I uploaded for the two sides of the c9kinetic did not have the text embedded properly.  They are fine to use but I have uploaded fixed versions labelled 101b and 102b.

2025-03-18 13:11 PST; I have had a few people report the posts in the frame breaking when rotating the barrel.  I suspect this is either a) a wall strength issue or b) the posts are too tight.  To address "a" please ensure you are using my recommended print settings.  And, to address "b" the post tightness, I have uploaded two alternative barrel designs.  These two new barrels have slightly larger holes for the pivot points.  The original design has 6.0mm holes, and the two new ones have 6.2mm and 6.4mm holes.  They are indicated as 062 and 064 respectively.  Please try them if you have had this issue, and please let me know if it helps. 

2025-03-19 09:43 PST; I have modified the sides to increase the strength of the barrel pivot posts.  Their outside diameter remains the same but the post will be stronger because of internal design changes.  These new sides are version 1v00c.
