HULA v1.0 Anti Vibration feet for Prusa Mk3/4, Core One (beta) & Prusa Bear

(IMPORTANT) - Please download the User Guide for HULA v1.0.

- I do my best to double-check and test the print profile I created. They are up to date with the latest changes made to the designs.

- If you wish to purchase ready-to-use HULA feet instead of printing them, please check the Vendor in Your Regional listing.

- Bearing washers should be installed with the smooth side facing the bearings.

UPDATE: 10 Jan 2026 This clarification is necessary to address ongoing misinformation. I am not associated with Triangle-Lab (also known as D-Force), FYSETC, Toaiot, or any AliExpress stores. There is no collaboration, partnership, or endorsement of any kind with any of these parties. I do not host files for any third-party hardware kits or remixes on this project page, and any instructions directing users here to obtain such files are incorrect and unauthorised. The only official vendors authorised for the HULA project are: - VoxelPLA (USA)

- VTC3D (EU)

- JC-3D & i3dprint (Australia)

UPDATE: 04 Feb 2025 With the update of PrusaSlicer to version 2.9.0 which supports multi-build plates, I decided to update the 3mf files making the project easier to print.

I have also added HULA for Core One (beta). At present, it is in beta stage as I need testers to try it out. You will require M3x8mm -12pcs (3 each) to secure the bracket to each corner of the Core One enclosure.

UPDATE: 10 Aug 2024 I have been gathering valuable feedback from users since the launch of HULA RC2. HULA v1.0 is the result of incorporating some of these suggestions to improve the design. - HULA petg parts are now easier to print and assemble.

- The TPU dampener design is improved for more linear dampening and is easier to print with less stringing.

- Cleaned up 3mf project files and updated the user guide.

I hope this will improve the user's experience of making HULA. If you wish to buy Ready-to-Use HULA feet or HULA Hardware Kit, I have partnered with regional vendors to offer them at an affordable price. I believe in buying locally and supporting local businesses. See below for the list of authorized vendors.

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 drew 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 (dependent on setup) and reduces the shake translated to the table and other printers. HULA for Prusa is designed with the same principles in mind.

HULA for Prusa Mk3 / Mk4 Prusa for Prusa Bear

BOM - F8-22M Thrust Bearings - 4 sets

- M3x8mm SHCS - 8pcs

- M3x8mm SHCS - 8pcs (Mk3/Mk4)

- M4x10mm SHCS + 3030 profile M4 slot nut - 4 sets

Printed Parts Files for HULA for Prusa have been prepared on PrusaSlicer. If you want HULA for other 3D printers (eg Bambu Lab, Creality, Voron) or to use OrcaSlicer/BambuSlicer 3mf multi-plate project files, you may download them from my MakerWorld page.

HULA v1 Prusa Mk3_4 PETG parts.3mf - Print build-plates 1 & 2. If you need spacers to level the feet print build-plate 3.

HULA v1 Prusa CoreOne(beta) PETG parts.3mf - Print build-plates 1 & 2. If you need spacers to level the feet print build-plate 3.

HULA v1 Prusa Bear PETG parts.3mf - Print build-plates 1 & 2. If you need spacers to level the feet print build-plate 3.

HULA v1 Prusa TPU parts.3mf - Please use 95A TPU filament (or close)

- This uses a 0.4mm nozzle but prints a line of 0.6mm for the dampeners. I have adjusted it in the slicer settings.

Assembly Instruction Please refer to the pdf user guide.
