quite loose, i recommend changing the scale ever so slightly to be more lego compatible

Really awesome. They snap together like normal pieces, they are great quality, and they are quick and easy to print. I will definitely print more of these bricks.

The bottom side works perfectly fine for me, but the diameter of the top studs needed to be increased to 5.1mm in my case

Printed well in our P1S, thank you!

Printed an 8x8 base piece - top is fine but underside does not work (too loose)

Printed using 0.25 nozzle and 0.15 layer height from PETG. Great work

Hi, what you're doing with the LEGO bricks is great. Unfortunately, I am looking for an inverted slope brick. Could you model one?

@MerlinMours_4186307 You should check out mine then, i got a couple

Works only if I set my flow to 105, otherwise the top buttons are too loose

Way too loose on top. Bottom is kinda good. (edited)
