The space on your shelfes is all used up with your Lego creations? Just print some of these hooks and continue on your skadis walls 😅.

I recommend to print multiple parts at once, so the individual hooks have enough time to cool down, have a nice surface finish and good tolerances. 

These building bricks have some quite tight tolerances to fit nicely together, on your individual printer you might have to play around with horizonal expansion and/or flowrates. For me they work fine as they are. I also recommend using something softer than PLA (PETG works fine for me) because the hard PLA can damage the ABS bricks over time and after some attachment cycles..
