Top Bar hive foundation starter

Rip a saw blade width 5mm deep along the center of your bar. Print one each of A1, A2, B1 and B2 to make one bar. Alternatively, print one A and one B if your printer can handle it. Glue the A and B together back to back. These bars are designed to fit my TBH (19 - 1/2" bar). For more information, visit https://www.thingiverse.com/thing:3126333. If your bars are shorter, trim out the middle section. If they're longer, you'll have a gap in the middle. The stops on the end of the starter strips keep the bar centered in the hive, so push them to 7/8" from each end. Before installing the bars, apply some hot beeswax and let it sit for 48 hours between two drawn frames on a flow. I initially had poor results without wax; I strongly recommend using it. Print at .2mm resolution with a .4mm nozzle, as I used PETG. The files have been updated to reflect the natural comb's center cell offset (1/2 cell size horizontally and vertically on opposite sides). The cells are now 4.95mm wide and 2mm deep. To ensure proper alignment, make sure the starter strips match across the entire bar.
