Inspired by Nimuno Loops successful crowdfunding campaign https://www.indiegogo.com/projects/nimuno-loops-the-toy-block-tape
I was curious how well flexible Lego's could be made at home. To my surprise it worked very well!
This design is parametric, click 'open in customizer' to make your own sizes.
The model allows you to make 'brick tape' which has the top side of LEGO studs, OR 'tile tape' which is the underside of LEGOs.
Filament Used: http://amzn.to/2np143M
I used a filament that is on the harder side of the flexible spectrum, TPU Shore 95A.

**UPDATED 7-2-17. Come to find out my printer wasn't properly calibrated when I created the original file, I've since changed it to reflect the newly recommended default settings.
The model currently reflects exact dimensions of real Legos and I do not recommend scaling it. If your printer makes the studs too small/large then try:
- Changing your extrusion multiplier
- Printing 'external perimeters first' to ensure that path overlap doesnt cause your critical surfaces to shift.
Printing with nozzle diameter .4mm or less. Layer height .2mm or less.
If all else fails and you want to rescue an imperfect brick, blast it with a heatgun for a few sec then press it onto a real Lego and let cool. Careful, this can easily ruin bricks too.
No heated bed necessary. The TPU filament I recommended is super easy to print with as long as you have a direct drive extruder. Printed on blue tape bed, no heat required.
Print with 100% infill!
If printing the tile tape, be sure to rotate it upside down so there are no overhangs. Flexible filament is hard to print supports for. (So no printing rafts either!)
