Confirmed working model and ready to Print!
this is for a 10 year old Honda weed wacker, the spool assembly has been discontinued, a friend of mine needs the replacement as his machines work fine still, this goes with the button i have posted on Thingiverse already @ https://www.thingiverse.com/thing:3688434
working on the inner spool @ https://www.thingiverse.com/thing:3704447
I'm not sure of the model name for the weed wacker but ill see if i can get it, as i said they,re about 10 years old and my friend uses them for his property maintenance company.
Print at 100% infill with placement as is, its designed thick enough to sand down/ clean up the outside/top of the lid from the rough raft like support you need to print it with and the bottom layer that usually doesn't stick well.
i used 25% support infill to save time, if you flip it around the important parts inside tend to wear out faster and debris can fill that housing potentially causing issues.
will post the pictures of the lid soon.
also i have one more part to make for sure and that's the center spool holder for this assembly, I may also try to design the bottom basket but it seems to be holding up just fine atm.
