Total Net Print Time: Approx. 50HR
- (Estimated as case of PLA, 0.4mm Nozzle, 0.2mm Layer Height, 40% infill and No raft and support)
Note: When at actual print, each parameter may be adjusted by your experience.
3D printing settings
Raft, Support, Layer Height, Infill: Depending on your experience.
But the parts having gear, small shaft and thin portion: 100% infill is recommended.
My models were printed by "idbox" using with 0.4 nozzle, 1.75 PLA.
This is the most challengeable item in the creations which I made before.
I do hope your success!!
