Huina 550 / 1550 / 580 Spring Coupler Remix

thingiverse

Spring-loaded coupler compatible with the Huina 550 / 1550 or 580 V1-V2-V3. It does not fit the 580 V4 bucket, but I will try to remix it if I can get dimensions. ********** For the 580, use the "580_Spring_Coupler_xxx.stl" files! ********** V5 has more clearance added for the bucket, lock, and bolts parts. It shouldn't need much filing or sanding. Also, a bevel was added 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. It also has 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, limiting the bucket throw too much. 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
