But design the tabs into small test pieces - don't waste tons of filament just for testing. The smaller the tabs, the bigger the effect of the printing and material flow error, while it may be less so for larger tabs.ĭepending on the size differences, you may need to experiment for each size of tab to find its perfect gap size. ![]() I also printed a set with a draft (sloped profile) but they didn't stick at all and would simply fall apart again.įor the second set I used a gap size of 0.2 mm and that gave me a perfect fit which needed only a tiny amount of pressure to get the pieces to fit, enough so they would not simply fell apart again.ĭisclaimer: The gap size needed won't be the same for larger puzzle tabs. I then went ahead and experimented a bit and printed 0.1 mm gap pieces which was still not enough and no amount of pressure would make them fit. I had no gap designed in and because of material flow during the printing stage (and the large effect it has on tiny details), did not fit at all. ![]() My first set of puzzle pieces (to test the different % fill settings) did not fit at all, using PLA and my small Duplicator i3 Mini printer. Every material and printer needs a different gap size for the pieces to fit.
