Prototype parts for Hop Scotch. Prints will require tree support to make tolerance. This is still in development and may not hold up to its own strength. Will update files and suggested materials as samples are printed and used. For one copy of the robot you will need:

Prints

• 1x: Chassis - TPU or PLA 

• 2x Shoulder Sleeve: PLA/PETG/Nylon - Carries RS00 arm motor, bolts into the chassis 

• 2x Shoulder Hub: PLA/PETG/Nylon - Attaches RS00 to Arm, sandwiched between Sleeve and Cap

• 2x Shoulder Cap: PLA/PETG/Nylon - Retains Shoulder Hub flange and is the exterior face of motor carrier sandwich.

• 2x Arm: TPU with many walls and high infill - Interfaces with shoulder and arm hubs. 

• 2x Arm Hub: PLA/PETG/Nylon - Inlays into arm, print this strong. 

• 2x Top Plate: TPU or PLA

• 4x Wheel: TPU... NOTE-this version will 'work,' but it will be bad. Try stretching some rubber bands around for grip.
