High-power underwater thruster Paddleboard thruster

This is a high-power underwater thruster that evolved from a friend's request. The motor is a modified 8120 drone motor, made with waterproofing brush coating and potting. Those with strong DIY skills can give it a try; the theoretical speed is 10-20km/h. I have prepared the printing materials, there are 3 3mf format drawings, all need to be printed. ABS material is for strong structures, so using strong materials is recommended depending on your environmental needs. PETG material is for cost control; if cost is not an issue, it can be directly changed to strong materials. The drawing parameters and materials are what I tested and used, and I found no issues. Motor dimensions are missing, please pay attention before printing!
