Shelf bracket with hidden screws

Shelf bracket with easy screw access during installation. It is quite strong, with supporting piece in place I cannot bend it in hands. I printed it with PETG, but it should work with PLA as well.PETG is tricky as this is quite long part, it lifted my PEI plate a little so it is something to consider when printing with PETG without heated chamber. Tolerances are tight, but parts from my printer fit without modifications, they are tight as they should be.Part is 170x170x20 mm and fits on A1 mini plate.If you like my design, live me a like and a boost, it's motivating! Enjoy, good luck!Boost Meif you enjoyed this design!
