🛠️ Features:

• Functional piston motion powered by a simple flick or twist
• Driveable by cross head screwdriver (electric drill or impact driver to enjoy the ultimate RPM)
• Compact design that fits comfortably in your palm
• Crafted with precision to showcase the iconic boxer-style layout
• Satisfying tactile feedback and rhythmic movement

🛠️ Print Tips:

• CLEAN THE BED and make sure a good adhesion for crank shaft assembly and bearing.
• After printing, the bearing might not work and fused together. TRY assemble and run first. Bearing are not necessary for a smooth running.
• i have 0 XY hole comp for all the cylinder heads and -0.1 for front pulley and rear interface assembly. This profile works well for me on the threads. If it's too loose or tight in your case, change the XY hole compensation (+ is increase the radius and - is reduce). Print one component to do the test (for example the clutch cover)

🛠️ Assembly Instructions:

• Assemble four cylinder heads with the crankshaft assembly

  

• Insert the position pins into lower block and place crankshaft assembly on the lower block.

• Put on upper block and assemble the rest parts with below sequency.

  

•  

  Then you are good to go! Enjoy the ultimate mini boxer. You will be amazed how fast it can go.
