GSO crayford focuser ZWO eaf bracket
thingiverse
Flat adapter plate for a ZWO EAF to be mounted a GSO dual speed crayford focuser in place of the coarse knob. The two centre holes are for the locking and tension bolt. The lock bolt is covered by the plate by default, the tension needed an M4x20 bolt to get through to the focuser to apply the right tension to draw tube and hold bracket. Captive nut slot is to have a second mounting point for the bracket onto the printed part. Maybe not necessary, adjust the pocket size in fusion360 for different nut dimensions. I pushed mine in with a soldering iron since it was ever so slightly too large for the hole. I printed in PLA and seems plenty strong. Fusion 360 link, modify the pocket size for your captive nut https://a360.co/2PKCLu8
