Wire Spool, in two parts, 8cm wheel diameter.
The picture says it all.
Its a wire spool, for those wire coils laying around. Its a 2 part print, that is glued together. No threads or anything fancy or complicated to print. Just glued together.
Print at .4 & 70% to make it sturdy.
The wheel diameter is 80mm and the shaft with its wheel base is 75cm high, making it eazy to print on just about anything out there.
The hole in the shaft is for M6-M7 rods.
Enjoy.
