Joist hangers install tool.

Update:  moved the whole thing forward to protect your paws!

Pre-supported tried to make all the angles 45 degrees so you would not need supports.  My creality 150$ printer is almost stock, prints this no problem with very little pilling or any other issues.  

Also added some “NS” with no support added, I like the Tree/Organic supports.

recommendations:  

5-line Brim.

20-40% gyroid infill

3 parameters with .4mm nozzle (thanks to CNC Kitchen)
