Alfons Proves I'm Improving...), puzzle envy set in and I was looking forward to trying that level 22 puzzle someday. As soon as I resigned myself to a long wait, the puzzlewillbeplayed site added a new level 18 puzzle by Stéphane Chomine with a similar format called Mini TV. The size was reduced by quite a bit compared to Alfons’ 6T Burr and I decided to print a copy to play with.
Mini TV consists of a frame with 2 core pieces that run through its center and 6 mini transverse pieces that slide along the outside and impede the movement of the 2 core pieces. I originally looked at using a 13 mm voxel size but the print time was much too long. Changing to a 10 mm voxel dropped the print time to a mere 13 hours.
The puzzle is very approachable and not too difficult to solve. Of course, since it was printed, it was an assembly challenge. It takes a lot less time to solve than to print. It took about an hour to assemble the puzzle.
The assembled puzzle is very attractive and like the assembly is very approachable as a disassembly challenge. The only issue that I had with the design is that the transverse pieces have a tendency to rotate out from the puzzle when they are moved from their initial position. You have to constantly ensure that they stay within the frame to avoid rotational shortcuts while solving.
