I am on a journey to create some of the most complex, versatile and facinating fidget toys. My prior model now with over 5000 downloads included 12 gears, and this new model includes 20 gears. Not just on the outside, but also on the inside!
This is the next version of my hYPER fidget toy, with the previous model currently on over 5000 downloads. https://makerworld.com/en/models/108623
EDIT: If you give up installing the final gear, I understand, it's difficult. I've added a print profile called “I GIVE UP” that includes an alternative to an inside gear. It's just a small cap that will easily slip in place of the final inside gear.
Be aware, this is fidgetty to put together too. It's not easy, and takes some patience. The print includes a tool to help place and press internal gears, but you will need to fiddle and use some force to put the pieces together, especially the last gear in a ring. The internal gear snaps together with the external gear, and for this reason I ONLY RECOMMEND 0.2mm layer height.
There are 20 gears in total. 10 on the outside, and 10 on the inside.
Improvements over the previous model:
- Fewer parts
- Prints in less than half the time
- Snap together gears so you can't over-tighten screws
- You can hold opposing gears in one hand to spin the toy
- The toy is a complete orb
- Gears on the inside
I've included 5 print profiles.
If you have good bed adhesion print the profiles without brim. If you're not sure, use a brim.
If you have an AMS I've provided print profiles to print in 3 colours, or one colour. The big gears (or outter gears) are colour 1, the body and tool are colour 2, and the inside gears are colour 3.
I've also included a profile with 3 build plates for 3 different colours.
Profile options:
- 1 colour no brim
- 1 colour with brim
- 3 colours no brim (RECOMMENDED)
- 3 colours with brim
- 3 Colours, 3 build plates
The multi colour print profiles will print each colour in order so there will be very little waste (just three purges in total).
Building tips:
- This is a difficult build. You will need to use some force to pop the parts together.
- Build the gears from one side to the other. Start with the bottom (where one gear goes into four), then work your way around. The last gear should be on the side (One of the spots where one gear interfaces with only two other gears.
- The last gear will be VERY difficult to pop into position. If don't build from one side to the other you will end up with multiple gears that are difficult to pop into position.
- The best method I've found to get the last gear into position is; remove the outside gear of either the top or bottom gear (where one gear interfaces with four other gears) on the opposite side of the last gear. The inside gear should be held in place by the four other inside gears, this then gives you enough wiggle room to force the last inside gear into position. Once that last inside gear is connected to it's outside gear, reattach the outside gear of the top or bottom gear.
- The last inside gear will need to be popped into position with force. It's possible but may seem impossible for some time. Trust me, it works. Orientate and push.
- The tool that prints with the core of the model is good for holding a gear in position, and for pushing down on the inside gear. I like to place the outside gear flat on the table then use the tool to orientate the inside gear before pushing down. Sometimes some extra tools like the back of a pen (or a fork or spoon handle) can help to push the inside gears down onto the outside gear.
- Make sure the inside gear has fully popped onto the outside gear.
Please enjoy! I love your comments and especially enjoy personal anecdotes of how you enjoyed the toy.
