Spring-loaded coupler compatible with the Huina 550 / 1550 or 580
V5 has more clearance added for the bucket, lock and bolts parts. Shouldn't need much filing/sanding. Also added a bevel to make hooking a bucket easier. If V4 worked fine for you, don't bother with V5!
V4 is beefier, reversed lock and quick-engaging. No need to push the lock to engage, just push to disengage. Also various improvements. This is the one to get !
Thanks to Guenter who remixed my design and gave me the idea :)
- I was made aware that the geometry was wrong for a 580, it limited the bucket throw too much, so a friend made a remix that i posted under "580_Spring_Coupler_Left/Right"
Parts Needed :
- 1x Clicky pen spring (Any will do)
- 2x M3x35 or M3x30 bolts to attach both halves together
