1/8" to 4mm Coupler

This is a coupler for steerable landing gear retracts from Hobbyking.com. It would fit 4mm pin from retracts and connect 1/8" music wire. You can use 3mm grub screws to lock the rods in place. This is originally designed for the P-38 plane from 3dlabprints.com

Please make sure to place the object with smaller 1/8" hole facing down on the print bed.
