HULA Anti-Vibration Feet for 3D Printers
HULA Anti-Vibration Feet for 3D Printers
Print Profile(3)
Description
IMPORTANT
- Please download the User Guides for HULA.
- I do my best to double-check and test the print profile I create. They are up to date with whatever changes I made to the designs. If you are using profiles made by others, please check if they are updated.
- if you want to purchase ready-to-use HULA feet instead of printing them, please check the Vendor in Your Regional listing.
- Bearing washers have to be installed with the smooth side facing the bearings.
UPDATE: 02 JUN 2024
I received feedback on the base plate for Trident that printing support can be a pain. So here is Option 02. No support is needed and faster print time. But raised the height by 4mm and fasten with only the M5 screw. Feedback on which options are preferred will be greatly appreciated.
UPDATE 31 May 2024
- HULA for Voron V2.4, Trident and Switchwire is now available. It is in a separate 3mf file “HULA for Voron 2024XXXX.3mf”.
- Please download the HULA for Voron User Guide for installation instructions.
- If you want to know more about HULA, download the HULA User Guide for additional reading.
- If you require the hardware (ie TPU parts. bearings & fasteners), the regional vendors are offering the hardware kit. Please order the HW kit for Bambu X1/P1 or Creality K1.
UPDATE 25 May 2024
- Uploaded HULA for A1 mini. It is a separate 3mf file “HULA for A1mini 20240528.3mf” for printing on the A1 mini.
- The TPU dampeners for the A1 mini are tuned to suit the lighter printers (under 8kg)
- Please download the HULA for A1 mini User Guide for installation instructions.
- If you want to know more about HULA, download the HULA User Guide for additional reading.

INTRODUCTION
Most 3D printers use rubber feet designed to absorb motors and engine vibrations. It does not do a good job of absorbing the force caused by the directional changes of the toolhead. I draw inspiration from seismic base isolators used to earthquake-proof building structures and designed HULA.
What is HULA?
HULA is an Omnidirectional Self-Aligning Anti-Vibration Foot specifically designed to dampen movement vibration generated by fast 3D printers. It decouples the printer from the table and dampens the horizontal XY forces of corexy & cartesian printers, preventing the printer from swaying/wobbling. This reduces the stress on the printer frame, improves print quality and reduces the shake translated to the table and other printers.

User Guide and Information for HULA
I have prepared a User Guide for HULA to provide information on printing & assembling. You can find the pdf file at the bottom of the writeup under the Documentation section. Please download it. I will try to add an instructional video soon.

There are 2 versions of F8-22M thrust bearings; 11 & 10 balls. I would advise getting the 11-ball version as it is more stable.
For this project, I used Voxelpetg+ and Bambu Lab 95A HF TPU. If you want to get the same filament I worked with, link below.

VIDEOS
Comparison Test between Bambu Lab Anti-Vibration feet (left) vs HULA anti-Vibration feet (right) - In this video, you will see that Bambu Lab anti-v feet cause the printer to wobble/oscillate. Where the HULA decouples the printer from the table and dampens the movement on the horizontal plane greatly reducing the wobbling.

Installation video of HULA for A1 mini
Hula is meant to be a fun and useful project for the community, and the way it moves always reminds me of Crayon Shin Chan 蜡笔小新 (クレヨンしんちゃん) who was my favourite manga during my university days.

CONCLUSION
To date, my designs are free to download for personal use. There is No Patreon, No Membership, No Clubs, No Subs and No OnlyFan (hahaha). If you like my designs and wish to contribute to my coffee addiction and help fund the filaments/materials needed for prototyping, doing any one of the below will be greatly appreciated:
- Post your make in the comments section and other 3D printing social media sites,
- A MakerWorld's boost,
- Purchase HULA kits from listed vendors,
- Buy me a coffee at Ko-fi or paypal.me
CAVEAT
As with all my designs, Prototyping and testing were conducted to ensure printability and meet my expectations. However, I understand it may and may not work for you. I would request that you read all instructions before printing and installing them at your own discretion.
