| Eight year old Jossilyn created a toy hammer for her sister Jasmine. Using SketchUp, she designed it by first creating a cylinder, then adding a rectangular shaped handle. One of the things I love about SketchUp is that you can design something without worrying about details like dimensions. Jossilyn's original design was a hammer that was over four meters in diameter, with a handle that was something like 11 meters long.  |  |
Jossilyn can focus on design, having only to ensure that the proportions look correct. She doesn't need to measure anything, and free of that burden, she can simply design. She put a lot of thought into her design, and although you may not see it very clearly here, she thought to rotate the handle about 90 degrees so that it would be easier to hold. You can download the design file from Thingiverse.
After I got the file, I simply used the SketchUp scale tool to reduce it to 10% of the original size. I also separated the handle from the hammer head so that it could be printed without support.
Print time for this was 6 and a half hours. I sliced it with .4mm layer height, and printed it on my modified Prusa i3, X3REX.
I did two other things with this print, that I haven't done before. First, I removed the Capton tape from the heatbed and printed directly on the glass. The tape was buckling and torn, causing annoying textures on the surface touching the printbed. I coated the glass surface with a lot of "goo", which is simply ABS dissolved in acetone, to hold the parts to the printbed. I also put a cardboard enclosure around the printer to prevent warping and layer separation. There was only a little warping on the handle, about .2mm on either end. I saw a few separated layers, but it was negligible. The parts came off the bed really easily.
Best of all, Jasmine loved the toy that her sister created for her!
