Quick release bracket for ZWO EAF to the Astro-Physics 3.5" focuser shaft. Pretty straightforward build, assembly is pretty self explanatory. I used Bambu PETG-HF. For the gear adapter, I used HIPS interface material with a Bambu AMS.
Requirements:
3mm x 6mm screws (2) - for attaching adapter to AP focuser body
3mm (4mm long, 4.9mm diameter) heat set inserts (2) - for attaching adapter to AP focuser body
2mm x 6mm screws (2) - for attaching gear adapter to EAF shaft
5x10mm magnets (8): https://www.amazon.com/dp/B075PMWGST?ref=nb_sb_ss_w_as-reorder_k0_1_6&=&crid=2QUGS7OSBA6WN&=&sprefix=5x10mm
Be gentle when removing the EAF from the shaft adapter. There is limited real estate on the AP focuser shaft to create a “grip” for my shaft adapter 3D model, it can slide off despite the 3mm screws being tightened down. It will hold, but if you're rough with it, it will pop off.
I added a second shaft adapter. Due to the limited grip area on the AP focuser body, I pulled the inner wall of the body -0.5mm to make space for tape. I put a strip of no-slip tape inside the shaft adapter, so it holds a little better than it did previously. https://www.amazon.com/LifeGrip-Resilient-Non-Slip-Traction-Comfortable/dp/B07PZFBG22/ref=sr_1_9?crid=2Z924P5ZURQ1Z&dib=eyJ2IjoiMSJ9.RPMLVd9lSOkMYkP4DTAe5tL4sA0XRxfKcZLvm5HdtXGTpkPIK-qdrPKDu5-myU9Ndw8d7FZSwsdY9Y71AixwLQDG42k7R9UpHFv7jtsiF28JNaErcFlDAh7frq3YOEW-j-24XPNQQN7apispoDyPgNNxZ654oSAE4e6sa5TnFVmvatf3oCHVby1SJNeSkyIJv7STLn1XZDpdASSVERcHduTVv8BXsc5adZEwWBskygbsb9fBc_iPQyGzu6Ozz5z9YXZYQZ0p3bcBsFxPilEWUV67Q9KY-xX7bc1FzpSEvko.Qj2rGXSQ0BUGSC1G2IHa9WejXpy0_MsYPzMW4ish0w8&dib_tag=se&keywords=no+slip+non+abrasive+tape&qid=1733695516&s=industrial&sprefix=no+slip+non+abrasive+tape%2Cindustrial%2C122&sr=1-9
