Mini Loader 1.1 (no supports, no hardware needed)

This is an all-wheel drive mini loader with shock absorption and a movable bucket, which needs no hardware. The springs are 3D Printed, and the press feel is quite firm~!! There are 2 print profiles, a standard version and a 1.5x larger version (with 3 walls). Some force is needed when installing the support arms~, but overall assembly is quite simple!!

2026.6.3 Update: The wheel axle has been changed to the easier-to-install 3rd generation wheel axle below, and the corresponding body and bucket support arms have been modified!!

The GIF below is an assembly diagram:

1. First, insert the bucket into the support arms and then into the body for easier assembly

2. Tilt the wheel onto one side of the wheel axle buckle, then use your thumb to press the red circled area, and your index finger to press the side of the wheel (using leverage) to push it in. The other wheel is installed in the same way!!

3. Then install the other components

4. If the snap-fit damping of the arm is weak, you can insert a small piece of paper into the gap before assembly to enhance the damping~

In the image below, the red circled area (spacing about 5.8mm) is normal. If there is severe collapse, please add supports yourself~, or check if there is an issue with the filament!!

Note: 1. Both PLA and PETG can be printed. It's best to understand the characteristics of these two materials before printing to avoid printing failures!! For example, PLA can become brittle if left for a long time or at low temperatures, while PETG has good toughness. Please choose the filament that suits you!!

        2. If it's for younger children, and the parts are small and easy to disassemble, it's better to glue them firmly with 502 or other adhesives to prevent them from being swallowed!!

        3. If there are no special requirements, please do not use your own advanced process settings for printing~ to avoid printing failures!!

If your printd part has local spaghetti, or the filament doesn't stick to the build plate, please recall if you touched that area (hands secrete sweat and oil, touching it has a very high chance of causing spaghetti)  or if the build plate is dirty. The solution is to search online for how to clean a 3D print plate!! If other problems occur, please describe it in the comments section and add pictures, so it's easier for us to solve it~  Otherwise, I can't imagine the situation = =!!
