These are inserts for the popular HF storage cases, #93928. I thought these might be useful for others who use these for storing their stuff so I uploaded it. I used the originals as a reference. There are 3 kinds of inserts. Big one, divided into 2 and then divided into 4.
These don't have the tabs on the bottom for easier printing. The tabs are there to stop the inserts from moving around if you have adjacent inserts that are missing. I never have cases with missing inserts so these tabs aren't necessary for me.
I printed them at 0.4mm height. They fit pretty good.
