after so many boxes and hasps I've decided to create my own mini lock.
and after about 10-15 tests i managed to get it also working, to be so small it has a good grip.
the file is optimized for a 0.4 nozzle, so far I had problem printing it with s3d but not with ideamaker, i suggest to look always at the print preview for gaps in the print (anyway few are normal in the inside part)
its cute it's simple and it prints in just 17 minutes.
20-30 mm/s speed or less
cooling at max
maybe u will nide a clamp or something similar to press close all togheter
if u like my work any support is appreciated, just uploading the make of this thing will incite me to continue sharing my works :)
