My kid's crib is at its last leg. I've already bought like a dozen of these, and that's the last kid, so this one needs to make it another 6-12 months no matter what. 

The shorter side is only a press fit on a wooden dowel, possibly with a bit of wood from the factory. I tried gluing it before, but it's a moving structure, so the glue gave way. 

This bracket will hold the bottom of the frame together to mitigate the problem. 

I totally overkilled it with 4 screws per corner. 

Printing

• I printed with 5 parameters and 25% infill. In a Grogu leftover color :) 
• Print upside down with a brim for clean corners. 
• Since taking these pictures I've chamfered the edges a little. 

Assembly

1. Remove one of the hex screws holding the bed in place. 
2. Slide the adapter from below and screw the hex back in. 
3. I predrilled all the holes to avoid splitting the wood. 
4. Use any screws, the holes are quite large. I used 4x16. 

Just because it's a baby-related product, I want to add that you're using this at your own risk.
