SpotMicro v2

thingiverse

Based on the increasingly popular Spot Micro design, I created a modified version to improve several aspects: I replaced all nuts and bolts with self-tapping screws (significantly easier and faster to assemble and open/close covers for access to electronics). Thanks to the self-tapping screw change, no more gluing of any part is required. The larger foot is now bigger on the inside, while the wrist is smaller (not noticeable from outside, but will provide better elasticity). I replaced the servo horn with those that come with the servos PDI-HV5523MG. I created a tester for these servo horns so anyone can check if they fit before printing a leg section. If you'd like to customize this design further, please find the Fusion 360 design here. # Hardware Needed Here's what's specific for this chassis version: You'll need a Raspberry Pi or other mainboard of your preference (link in the list takes you to where I bought them). - **12 x PDI-HV5523MG servos** - If you have other servos, make sure they fit the design using ServoHornTester.stl - **M3 self-tapping countersunk head screws** - Get a kit, you'll use them for other prints too! These are used to link every printed part together. - **M2 x 6mm self-tapping countersunk head screws** - Make sure they're 6mm long and have a countersunk head. Use these to screw the servo horns to the printed parts. # Heading Parts to Print Some parts on this design are compatible with the original SpotMicro. I'll mention that in the list of things to print. Note about file naming: - **F** = Front - **B** = Back - **I** = Inner - **O** = Outer - **L** = Left - **R** = Right _Servo Horn Tester_ To avoid printing countless hours just to find out this design doesn't fit your servos, I'd recommend printing the servo tester. It prints quite fast and you ensure every other print will work with your hardware. - **1** x ServoHornTester.stl _Body_ - **1** x Chassis_Baseplate_v2.0.stl *(compatible with SpotMicro v1.0)* - **2** x Chassis_Side_v2.0.stl *(compatible with SpotMicro v1.0)* - **1** x F_I_Shoulder_v2.0.stl - **1** x F_O_Shoulder_v2.0.stl - **1** x B_I_Shoulder_v2.0.stl - **1** x B_O_Shoulder_v2.0.stl _Legs_ - **2** x L_HindLimb_v2.0.stl - **2** x L_MidLimb_v2.0.stl - **2** x L_Wrist_v2.0.stl - **2** x L_MidLimbCover_v2.0.stl *(compatible with SpotMicro v1.0)* - **2** x R_HindLimb_v2.0.stl - **2** x R_MidLimb_v2.0.stl - **2** x R_Wrist_v2.0.stl - **2** x R_MidLimbCover_v2.0.stl - **4** x Foot_v2.0.stl *(Better if printed in TPU or any elastic material)* _Covers_ - **1** x Cover_Top_v2.0.stl - **1** x Cover_Bottom_v2.0.stl - **1** x Head_RPiCam_v2.0.stl - **1** x Butt_Empty_v2.0.stl
