I printed the longest one. works great

great design. tracks easily fit inside the columns

works great. the extra long tracks are very useful

don't print directly from bambu handy since you need to pick and choose certain pieces to match with others, and some pieces require multiple copies to match a single one of another shape

the one with tiles does not work well because some pieces are too thin and end up breaking apart. the one without tiles is much another and stronger

works very well

the tip is a little fragile

very good. the nut doesn't always fall on its own though
