Stronger Shelf Bracket
by richard_j_m, published
Decided to make an even stronger shelf support. Very impressed by the rigidity of the print.
This is a design inspired by a failed print of http://www.thingiverse.com/thing:34422. The object came unstuck just after the printing the bottom half. I was so impressed by the strength of the unfinished print I decided to make my own design that was half the size but also with a much larger surface area on the print bed to try to stop the object moving during print.
Please Note: The brackets I've printed with PLA have flowed somewhat in the hot environment of my workshop (30-40C) so I'm reprinting in ABS which should last longer. Just something to be aware of.

Printed it with PLA at 175C, 0.35mm J-Head with a fairly slow print speed. 0.25mm layers and 20% infill.
As you can see this can hold a fair amount, very happy with it.
