Metal Bed Frame Mattress Support

This is a support bracket to be used with metal frame bed frames. 

I have two of these bed frames and I have designed two brackets that fit each of them. I cannot guarantee they will fit yours so please measure. I have included images with the distance between the bed frame parts that these will fit on. 
 

I have a queen sized frame that uses the 13.5cm brackets.  
My Full size frame size uses 9.7 cm brackets. 

For both of the frames I have, the bottom and top measurements were identical. 
Yours may be different. 

If only your corners are a problem, just print 4.  However if your mattress tends to slip through the frame supports on either end, I suggest putting 4 on each end (8 total) to keep the mattress from falling through. 

*I used 5 on mine because the center support was lower than the rest of the frame supports on my queen frame and I wanted the mattress evenly supported. 

Please print with 4 walls and increase infill to 20%.  Model should be printed as it is oriented in the stl files for maximize strength.

You can print these in regular PLA because although they do support a mattress, the weight is distributed and these are only designed to be used at the top and bottom of the bed. 

You can also print these in PETG or ABS for even stronger structures. 

I recommend printing a single bracket first to make sure it fits properly.  It also only fits in one direction so be mindful that the outer bed frame is wider than the inner supports. 

I made this support structure in TinkerCAD.  If your frame is a different size, feel free to use this concept design to make a custom one for your frame.  This design works very well (in my opinion).
