Any experiences with Pela Blocks (lego compatible, parametric blocks)?
Nice find! I can only share that I found PLA to be very stiff when printing (not) Lego blocks, making assembly difficult. Have not tried PETG, but read that ABS has just the right amount of flex and give for this application. Of course, if you're just using them for one-time builds, this is less of an issue. You might try using a bit looser fit which should be easy given the OpenSCAD source.
Well this is one I grabbed. Printing calibration block in PETG now.
I've printed other Lego compatible stuff and ABS was so far the best material for that. PLA is too stiff, PETG flex too much under certain conditions.
I'm wandering how long it will take until this site will go down. Lego is on rampage right now in regards to "compatibility".
