Hello,
I am using these motors with the XRP platform. My competition rules are very loose to promote unique ideas and mine is to create a gear locker to lock the two shaft gears together to cut my reduction ratio in half. Im looking for help getting the dimensions of the gears inside the motor so I can 3d print a reliable and suitable piece for my project. Any help is greatly appreciated.
You’d need to disassemble the unit via the screws
But I’d sooner just couple them and have its output paired with a single external reduction gear…3D printed internal gears are probably going to struggle (they are metal)
First disassemble it carefully. Take photos at each step to aid reassembly. Measure all gears using a digital caliper. Note the outer diameter, teeth count, thickness, and bore diameter. Record the center-to-center distance between the two gears you want to link. Most small motors use simple spur gears. Your 3D-printed locker should match the gear pitch. Slightly oversize the piece for smooth meshing. Use strong materials like PETG or Nylon instead of PLA. Orient layers along the force direction for durability. Test the fit and refine dimensions as needed. You can also scan gears to create accurate CAD models. Be aware that modifications may reduce motor life.
