Chuck Puzzle (Level 3)

thingiverse

A traditional Chuck Puzzle crafted in 3d plastic All the pieces fit in a specific pattern using only 3 sizes of pieces, and a few "Keyed" pieces to lock it all together To print the puzzle, you will need multiple copies of various pieces 6x Size3 17x Size2 1x Size2-Key 28x Size1 2x Size1-Key I recommend printing in batches of 6 I have the pieces designed with 0 tolerance, if you have trouble with a tight/loose fit, you may need to tweak some settings I can upload level 4 and 5 if anyone wants an additional challenge Print Settings Printer Brand: SeeMeCNC Printer: Rostock MAX Rafts: No Supports: No Resolution: .1mm Infill: 100% Notes: I used Slic3r within Repetier Host Printed with ABS bed temp: 84 extruder temp: 225 using a .35mm nozzle slic3r has a setting called "XY Size Compensation" I set this to -.15mm to "shrink" the piece and get a nice fit. Make it more negative to get a looser fit How I Designed This Designed in Autodesk 123D Design I'm using 2mm as a base measurement for all pieces. All dimensions are multiples of 2mm each additional piece is 12mm longer than the last The keys are made by taking a 1mm chunk out of the sides of a piece This puzzle can be made even more complex by making longer and longer pieces
