About this 3D model

this is the second part to my printable mendle frame i still have a few parts to make but with these pieces you can print out a frame, i am still working on the rod holder parts but i have the easy one for the top done you can see how it is supposed to look by looking at the other one in my profile, i like the idea i just need to do some more work on it still. in the picture there the 4 pieces are 1 corner piece 1 of the straight pieces , the other 2 are going to be rod holders, the one with the parts sticking out is for the top of the y axis and the other one there i am still trying to get my angles right on so that i can make sure it is printable i will be for the x axis rods but i still have more work to do with him.
