**Multi-stage compound gearbox with sequential gear reduction.**

The input gear with a radius of **4.75 mm** drives the first compound gear with a radius of **14.75 mm** on one side.

**_Each intermediate gear is a single solid part with two different radius:_**
- 14.75 mm on one side (driven side)
- 4.75 mm on the opposite side (driving side)

The large side of each compound gear is driven by the previous stage, while the small side drives the next stage.

This principle is repeated through all intermediate stages of the gearbox.

The first gear is a single 4.75 mm input gear, and the final gear is a single 14.75 mm output gear, without a secondary driving section.

**_All Paid STL's in 1 subscription_** - [https://patreon.com/ro_qd](https://patreon.com/ro_qd)

This design provides step-by-step speed reduction and torque multiplication in a compact and mechanically rigid structure.

With **_each stage, rotational speed is reduced by approximately 3.1×_**, while output torque increases accordingly.

The final large gear transfers motion to the central output shaft.

The gearbox is designed for smooth operation, stable alignment, and reliable power transmission.

Optimized for FDM 3D printing and DIY mechanical projects.

MULTI-STAGE COMPOUND GEARBOX 93:1 | HIGH TORQUE SPEED REDUCER

GearBox.stl

Sometimes we humans need to build machines with the sole purpose of demonstrating the effects of gravity on a steel sphere. This is a machine that happily fulfills that purpose.   Be mesmerized by the combination of engineering and physics resulting from the simple motion of turning a gear.  Watch as the steel ball bearings gain potential energy as they're being lifted by the big wheel, only to be converted to kinetic energy as they roll around the well and tumble back to the bottom.  Be amazed by the fact that this whole thing is 3D Printed.

This download includes all of the STL files needed to print your own Gravity Well desk sculpture and requires no additional tools for assembly. This piece will bring you some needed meditation reminding you that there is order in the universe after all.

You will need to purchase 1/2" ball bearings (or 12-12.5mm) which can be found here:
https://geni.us/halfinchBallBearings 


Recommended print settings:
Layer Height: 0.2mm (All Parts except Well) | 0.1mm for Well 
Nozzle: 0.4mm

The largest file size is the dish, which is 205mm x 205mm.  All the files have been pre-oriented to save you some set up time. 

The Gravity Well

Base.STL

A fully 3D printable version of The Toronto Strandbeest, inspired by the huge one I made for a Youtube video (See below).

Based off the original invention by Theo Jansen, the Strandbeest is a mechanical walking creature that harnesses the power of the wind.  This particular version uses a large 3D printed rotor at the back.  The power from the wind is transferred through a gear box and to the main shaft that drives each leg module.

The Toronto Strandbeest is capable of walking completely on its own.  It can also sit comfortably on its display stand (included in the STL package) so you can watch the walking mechanism do it's thing!

The STL File:
Prints on all standard 3d printers, requires no additional tools or assembly, and assembles in seconds.

This video below shows you how to assemble this beest!

Full Parts list is included in the read-me file to make it easier for you to organize your prints.

**Recommended print settings:**
Layer Height: 0.2mm
Nozzle: 0.4mm
Infill: 15-18% 
Total Material: ~300g
Min. Bed Size: 180x180mm

The time to print and fully assemble is approximately 1 hour and 15-30 minutes. 

Gears and core may be printed in any material. 
Clips should be printed in PETG. 
Tool can be printed in PLA. 

Place the clip into the tool and use the tool to place the clips directly into the holes of the gears. Make sure you go directly into the hole to avoid splitting, breaking, or over-bending the clips. I would recommend that you print out additional clips to ensure you have extras when you mess up. 

Once the clips are installed, you can place the gears following the numbering located on each gear and core side.

This box was born as a special collaboration between me and [3D Printing World](https://thangs.com/designer/3dprintingworld), where I sculpted the Magnolia flower on top and he designed the mechanical box.

This box is an outcome of a special request for a marriage proposal of a great member of the 3D Printing Community.
**Caleb**, the producer and costar of [HotMakes](https://youtube.com/@HotMakesLive?si=8Z-TZeVbEQwuodcW) wanted a mechanical ring box that somehow incorporates his girlfriend (now fiancés) favorite flower, the magnolia.
- - -
This type of mechanism **3D Printing World** created is perfect for a magnolia since the number of petals on the flower line up perfectly with 60 degrees.
Each of the six petals on top are connected to an outside ring gear and an inside torsion loaded spring gear.
When you hold the box and rotate the ring gear the pedals open. When you let go of the gear, the spring loaded gear forces the pedals to come together.

_**The bottom of the box prints in place.**
Use a .4mm nozzle and .2mm layer heights or smaller. You will need to print three double pedals and three single pedals. You will also want to print the shim which will help to glue the pedals squarely onto the shafts. None of the parts require supports. **There is also 3MF files for dual color pedals.**_

_The top petals glue onto locators on the top of each shaft to glue it together.
Make sure you alternate between single and double pedals.
**See the assembly video for assembly instructions.**_

Much thanks to **3D Printing World** for creating this brilliant and magical mechanism that makes the box so unique, without which the magic would not have been possible.

Some may call it the trippiest thing to come off of a 3D Printer since the conception of 3D printing. The Exploding Circle, previously existing only as a 3D rendering in the world of the YouTube, has been brought to the real (simulated) world.  After repeatedly kicking the behind of its creator, the gears have aligned. Once every 2pi radians, the segments of the circle come together, only to re-explode as the crank keeps spinning.

The Exploding Circle engineered kinetic sculpture is a mesmerizing example of how you can use spur gears, bevel gears, and planetary gears to create interesting motion.

This download includes all of the STL files needed to 3D print your own Exploding Circle sculpture and requires no additional tools for assembly. WD-40 or another type of lubricant is recommended for smooth operation.

This Video shows you how easy it is to assemble!

Recommended print settings:

Layer Height: 0.2mm
Nozzle: 0.4mm
Infill: 15-18% 
Total Filament: ~0.47 kg
Largest Part Size on Bed: 200x200mm
Tallest Part: 106mm

**All the files have been pre-oriented to save you some set up time! All you need to do is drop the parts into your slicer and hit print!  This download includes pre-arranged layouts for 205x205 (or larger) beds for easier printing!

The Exploding Circle

Build 1.stl

This is one of my all time favourites- instead of a pendulum, this escapement uses a ball bearing rolling along a track to keep time.  At the end of the track, the escapement hits a trigger which causes the track to slant the other way, starting the cycle again.

The video below shows how easily this mechanism can be assembled!
