Edit: Due to an issue plugging 4 sections together for an entire floor, I had to remove the original tabs. The interlock pieces still work great without any issues.
I made it interlocking so that glue is no longer required.
There is a test piece, please print this first to make sure your printer can handle printing the parts at the size you desire.
This has been tested and printed without any issues at both .2 and .24 mm layer height, 2 perimeters, 20% infill and speeds of 30mm/s for external walls and 60-80mm for internal walls and infil. I did 5 top solid levels. This is mainly to prevent any kind of sagging, causing holes in the floor because I'm only using 20% infil.
IMPORTANT: WARPING
If your printer has any issues with parts warping off the print bed I highly recommend using a brim for these. It means you have a little bit of shaving with sand paper, file or an Xacto knife but any warping on the interlocking pieces or on the floor tabs can completely ruin the locking mechanisms. These parts have a large floor footprint and a brim makes a big difference in preventing warping. I used five rings of brim for my prints and they worked great on my printer. Adjust as needed for your own.
I hope you find this helpful and happy printing!
