Fridge Toys: Fishtravel

The challenging part with this thing is how tiny the details of the printed drawings get when scaled down to fit on this. The often used linewidth of 0,4 mm will likely smear the lines together and pile a heap of plastic. I recommend to go down to 0,3 mm linewidth in the slicer.

For me, using a 0,3 mm nozzle worked best. A 0,4 mm nozzle will do but you see the difference.

The model is meant for 2 color printing with a single extruder, you change the filament at a certain height. The base has 4 mm and then the drawing follows with 0,3 mm. 

This is a change from my former formula of 0,4 mm height of the drawing part and doing it in 2 layers a 0,2mm. I also had a word with inkscape about widening line widths and hope this works better now.

Slice it with a layer height of 0,3 mm.

and in the slicer insert a “Change filament” before the 15th layer (check the preview where the drawing on top starts!) and thus you can print it black on white or what colors you prefer.

The magnet goes into a hole on the back, it's made for 8mm diameter, 2mm height neodym magnets. The hole may need some sharpening of the edge after print and should hold the magnet tight without glue.

Print it with (tree-) support for the magnet-hole.

Going down with feed rate and temperature for the last  layers may help avoiding stringing.

The drawing follows a creation of Hieronymus Bosch.
The thing is 55 x 39 x 4,3 mm.
