Samsung RL37WBSW Door Shelf Genuine spare part

This Samsung Door Shelf is for the RL37WBSW model and can be mounted on all spots in the door.

Motivation

The original Samsung shelf part is designed weakly and I assume targeted obsolescence. Samsung also decided for a very complex design, with many round surfaces, which are hard to copy.

I used a ‘parallel projection’ to paper, which i then photographed and imported into fusion 360 and used as a basis. Turns out I got it right on the first try, nice!

Design

My design can be used as a base for any platform, this is why i provided the f3d source code. The fit inside the fridge is perfect, when using a PETG print with 0.2mm nozzle. The front was designed with 4 perimeters in mind so it has no inner layer.

I recommend to print design v2 as it has no hollow chambers caused by 15% infill since can be printed with 100% infill. BUT: you need to calibrate your printer very very well to be able to print at 100% infill, normally the infill is a place to normalize the planes in a way that irregular print surfaces can still be used. This normalization also happens with 100% infill but this needs much more z-space to normalize if huge volumes are printed like the base part of either print for instance.

Print v1

Make sure you orient the print towards the user with the front of the shelf to not have seam on the front (as shown in the picture of the printed shelf installed).

When using prusaslicer I would use these parameters:

• Orient bottom to bottom
• Orient front of the print towards the user (seam, the position the printer changes layers, by default goes to the back of the item). I did this wrong in my first two prints, see the photograph)
• I used a 0.2mm nozzle
• Use 4 perimeters (this causes the bottom layer to have exactly 1 inner layer where the print can ‘normalize’ the surface)
• Print with PETG transparent
• Use seam draw on the back side, like the mount point for example
• Don't use abrasive nozzles containing lead as Brass nozzles (instead use stainless steel or hardened steel nozzles). I used a Revo ObXidian from e3d but not sure if this is food safe.

Print v2

• All like v1
• Use 100% infill

Disclaimar

Make sure you understand the health risk of this:

• Don't use materials which are not food safe due to chemicals or colors not suitable for food
• The print in layers causes gaps which can be filled by bacteria which can cause health issues and are hard to clean
• The nozzle could cause lead to contaminate the print when using the wrong materials
• Your kitten could die if you accidentially leave it in the fridge while installation.

That being said, I take no responsibility, use at your own risk.
