Expandable shelf bracket

I needed a shelf bracket with a depth of at least 35 cm that can securely hold a weight of 10 kg. Since it's apparent that such a product doesn't exist here, I have developed a shelf bracket myself and am sharing it with you.

The extensions are modularly designed, allowing a shelf bracket to be assembled at lengths of 20, 30, 35, and 40 cm as desired.

You need to print these parts for each bracket at the following lengths.

Picture 1

Just the bracket without extensions.

Picture 2

Slide extension a2_100 and a1_200 into the bracket holder. You may fix them with small screws.

Picture 3

First, slide extension a2_100 and a1_200 into the bracket holder, and then slide the two extensions shown here on top of them. You may fix them with small screws.

Picture 4

First, slide extension a2_100 and a1_200 into the bracket holder, and then slide the two extensions shown here on top of them. You may fix them with small screws.

Printing information

Layer height: 0.32mm (0.6 nozzle); 0.20 (0.4 nozzle)
Infill: 15%
Perimeters: 3 (0.6 nozzle); 4 (0.4 nozzle)
Support: none
Brim: recommended for printing the bracket

Important: When printing the bracket, the entire height of the print area of a Prusa MK4 is used. Therefore, you should not have anything attached to the printer's cross frame that limits the print height.

I am looking forward to your Makes! :-)

And maybe you would like to support me with a small donation. Feel free to use the support button on the top right of this page. I myself donate one or two Euros to each designer for an interesting model that is worth five stars to me.
