Forklift with rotation for EEZYbotARM MK2

This is a remix of the Adapters with rotation for EEZYbotARM MK2 (Mantis Gripper, etc) (on Thingiverse) to fit the EEZYbotARM MK2 robotic arm (on Thingiverse). It gives you the option to pick up scaled down pallets or anything else you can think of to pick up with forks.

I used a TGY-R5180MG servo from Hobbyking.com in the "adaptor_base" to make the forklift attachment rotate.

For pallets I created a 1/14th Scale Standard US Pallet here

and a

1/16th Scale Standard US Pallet here

They are both a good size for this attachment.

For the pallets make sure you print the one of each that has the "planks" (deck boards) underneath it as well as on top. Otherwise, they will just fall off the forks if you rotate the forks.

When slicing there is no need for supports EXCEPT for the "adaptor_base", if you orient the pieces the same way that I did in my slicer (see photo in the photo section).

**UPDATE (March 2026): I have included a second variation of the forks STL to this model. The original version of the forks is listed as "forks_x2", this style of forks is the traditional straight forks found on most forklifts. But, I have found that when in movement the pallets tend to slide off the end of these forks. To help alleviate this, I have included an alternate STL file called "fork_(modified)_x2" which has a little bit of a lip on the tip of the fork. This helps a little bit with preventing the pallets from sliding off the forks. The pallets will still slide off though, if the arm jerks around when in movement. You can use either style of forks when printing this model, but whichever one you choose you will have to print two of them.

Post-Printing =============

Before assembly, super glue the "backrest_adaptor_bottom" and "backrest_adaptor_top" into the corresponding grooves on the "adaptor_ServoMount".

The "backrest_adaptor_bottom" will glue into the smaller of the two rectangular grooves on the "adaptor_ServoMount".

And the "backrest_adaptor_top" will glue into the wider of the two rectangular grooves on the "adaptor_ServoMount".

Before you glue the assembled "adaptor_ServoMount" with the "backrest_adaptor_bottom" and "backrest_adaptor_top" to the "backrest" make sure the "backrest" is orientated the proper way.

The long flat part of the "adaptor_ServoMount" should be on the top pointing up to the top of the "backrest".

Super glue the ends of the "backrest_adaptor_bottom" and "backrest_adaptor_top" into the corresponding rectangular grooves on the back of the "backrest".

After the "adaptor_ServoMount", "backrest_adaptor_bottom", "backrest_adaptor_top", and "backrest" have been correctly glued together you can proceed to assembling the rest of the Forklift Attachment.
