Owl on Lego
Description
I made cushwa's Owl smaller (about 40%) and put it on top of a 4x3 Lego.
Another version sits on a 4x3 Duplo.

Instructions
With a recent good printer, this is can be printed decently enough. However, some details won't come out right, e.g. the hole in the nose. If you own an older printer (Darwin generation), try the Duplo version.
I printed the Lego version twice:
* 0.25mm layers
* 15% fill
* 15 mm/s first layer (and nozzle real close), 80 for the fills and 35 for the perimeters.
* PLA at 210 degs C.
Then I made a variant: horizontal and vertical half-layers for perimeters. The result was worse (owl to the right in the picture with both). Probably slicer settings need to be changed more radically to get this right. Maybe less speed, maybe a higher extrusion rate, skip horizontal half layers, ....
Sorry for my usual bad picture quality. Yes - when I have time - I will some day buy a camera.
The Lego/duplo bricks were created with OpenScad using Doblo factory (see thingiverse.com/thing:2106). The Lego version has tight fit (at least with my printer/my settings) and the Duplo version more loose fit.

Love it. I've been meaning to print the owl...this gave me a reason to.
I printed in 0.3 mm layers 10% infill 0 shells at 80 mm/sec with the sailfish. I need to tweak my filament diameter as it's off a little...but this snaps to legos perfectly.
Nice print. My kids love it!
Cool :)
BTW, if you have some programming know how, adjusting Lego/Duplo parameters in the openscad library is not very difficult and you rather could generate new bricks if you want a perfect fit. Unfortunately, even changing one little slicing parameter can change fit...
The bricks used here are made with one line of code.
