Wooden bookcase shelf support

Did the removals company also lose one of the little wooden blocks that holds up each end of the shelf in your bookcase?  Well, here's the part for you!

I modelled it in Tinkercad and it printed in no time at all on the Bambulabs C1 Carbon.  I printed at 0.28mm layer height, 5 perimeters and 5 top and bottom layers, along with 25% grid infill.  It's absolutely bulletproof!

If there is one other household who has the same wooden bookcase, and they lose one of the blocks, then here's the one in a million fix.  Enjoy!
