Bed barrier or rails for children's bed

Hi Everybody,

When my kid turned 2 years old we gave bought him a 60cm tall bed, plus the matress it became a 85cm tall bed. So we had to buy or make some bed barrier to protect him. The ones in the market where mostly expensive and short, did not covered enough of the edges and where a risk for a so tall bed. We take the first option, make it!

Some of the principles the design had to cover were:
- Cover almost all the edges of the bed.
- Be high enough.
- Be resistant to tremendous kids.
- And very important, had to have the possibility to pivot down the barrier in order to make the bed.

You will find a set of pieces to use with 32x32mm wood battens:
- Corners: High and low, with and without connections with laterals (to cover right and left the same kind of corner you just have to invert the model in the slicer).
- Middle pieces: High and low, with and without GoPro connections.
- Bed restraints: GoPro kind of connection.
- Bedroom wall connection: 2 pieces. One is the plastic connection to the barrier, the other one is a simple plate for being made with TPU and have the damping function.

BOM:
You will also need screws. The number will depend on how long you will make the barrier:
1) GoPro base: 5 wood screws of 4mm diameter, and 1 M6 screw and nut with hexagonal head.
2) The rest of the models use 4mm wood screws no more than 30mm long or 15 if your are going to put screws in both sides. Some of them has an extra hole of 5mm to put long screws grabs the 2 wood battens.

HOW TO PRINT IT:

This may be critical. The first thing you must consider is that once you put the wood battens the lever force that your kid can apply on the corners and the restrains is huge. So, the most important thing to take into consideration is MAKE THE PIECES VERY STRONG. That means:
- Thick walls: Mine are 2mm thick, with a 3.5mm walls, that means that the walls of the corners does not have infill. All wall!!
- In case of infill: not less than 40%.
- Material used: I use PLA because it is strong. Use the best and strongest you know.
- And the most critical part: Make sure you got an spectacular layer adhesion. It may have to be printed slow? so be it!!! huge temperature? do not doubt it!!

The problem is that if your kid leans its weight against the barrier and it is not strong, it will broke and your kid fall down. In my first testing of the material, one of the reasons to weak walls was no chosing right in what direction place the model in the printer, the direction of the layers. My suggestion:
- All the corners and middle restrains with GoPro kind of connector, make the connector be parallel to the bed. This way the connector will be strong and capable to sustain the weight of the kid.
- The bed support with GoPro connector, the same way it would be placed in the bed.
- The corners with a lateral connector, the connector shoud be in vertical, because it will have to face huge lateral forces. This way, those forces will be contained with the layers in perpendicular, the right way.
- The support for the wall: In the pictures you will see that mine is broken. If you place the model in vertical in the printer, once you tighten the screws the layers will separate. But if you place it in horizontal the layers will be weak against the lever forces of the barrier. Sorry, but you will have to try your best judgement here.

Right now I can't think in anything else to tell you. Once I read questions and comes to mind I will update the instructions.
