Boat Shuttle v2

cults3d

A sleeker design than the previous one, but the length of the bobbin compartment is shorter, and this one will definitely require some support and sanding as none of the sides are totally flat. The bobbin compartment is only 120mm long so you will need a shorter bobbin. Printing orientation is upside down to provide a clean, smooth top finish. For Ender 3 v2 or similar sized printing bed, you have to rotate the shuttle 45 degrees to safely accommodate the size. Approximate dimensions: Length: 260 mm Width: 40 mm Height: 30 mm I have only printed it at low quality, 0.28mm per layer. It took 6-7 hours and around 80 grams of filament. At higher resolution, the bottom surface will probably look much smoother. To make it more resistant to damage when dropped, you may want to increase the number of walls. Using PLA+ and with only 2 walls, it did survive a 3-foot tall dropped onto a wooden floor twice with no apparent damage. I do not know about concrete floor. I had to use a tree support which I thought will provide the cleanest slot with minimal post processing like sanding the edges so the yarn or thread will not snag. The other notches and screw hole do not need any support. Installing a bobbin/spool holder using a G.I. wirehttps://youtu.be/iwfy2GQqnGY Shorter bobbin shafts are provided here.

Unfortunately, when I printed it, I forgot to provide a slot for the thread to pass through. The STL file comes with a slot, and not a hole.
