Working on Mongoose 38 today. 3D printed motor retainer, and 3D printed drill guide.
This motor retainer fits Loki 38 plugged bulkhead. I don't know yet how much the motor heat will affect the retainer, so I'll use a washer or something on the first flight to make sure I have good retention even if it melts. I will attach recovery harness to the motor as well, so at least three things have to fail to lose the motor.
Line 'em up and drill.
Pretty good alignment.
I haven't decided on countersink vs counterbore yet, so I'll just leave the hole as is for now.
