Cữ nối xếp chồng cho kệ Trofast đã sơn (Stacking Adapter)

I created this model from scratch with the shelves and some calipers. I view https://www.thingiverse.com/thing:5598290 as the inspiration for it (but that model does not fit the painted Trofast shelves that I have)

You will need to print 2 copies of the body and its mirror image. I printed in PETG with 0.15mm layer height. Also it is possible to minimize the amount of support needed when printing by placing the models vertically. The attached .3mf file can be opened in PrusaSlicer and has the models arranged in this way.
