These two puzzles require about 30 moves to remove (or insert) the first piece.
You can choose 3 levels of difficulty for each puzzle and the video below gives more details on the puzzle and difficulty levels.
To solve, no piece requires any rotations. That is you move parts left/right, up/down, back/forth. However, the Etrier puzzle requires you to rotate the two C pieces to enter or exit the plate. There are no other rotations required.
For the hardest difficulty, print the “no hints” versions of the parts. It is up to you to determine how to orient the pieces and arrive at the final topology. This is only for seasoned burr puzzle solvers.. I don't recommend this method. I, personally, seldom solve these puzzles in this manner.
The easiest version is a “take-apart” version where you fully assemble the parts using a 2-Part plate. You place the parts inside the frame and then either glue or screw the frame together. See the video for detailed instructions.
In the medium difficulty, use a one piece plate that has hints on the underside which show how the C and H pieces are oriented. You then need to place the 4 pieces inside the plate in the correct orientation. For someone who has done some burr puzzles before, this might be the most enjoyable, if you are looking for something to keep you occupied, on and off, for a few days.
I built both puzzles in PLA using 0.2mm layers, 3 perimeters, 4 top/bottom walls. I used 40% infill for the pieces, just to give them a bit of heft. I use 20% infill for the plate. I printed the plate using 2 colours with manual color changes.
The screws I use for the 2-part plate (for least difficult version) are M2.5x8mm (10mm also work) which can be obtained from Amazon or AliExpress at little cost. A 2mm hex screwdriver works well with the socket head M2.5 I use.
