1-2-3 blocks (metal blocks 1" x 2" x 3" in size, or metric 25mm X 50mm X 75mm) are commonly used in machining. Many woodworkers also use them as a convenient aid for spacing and supporting work. However, machinist 1-2-3 blocks are expensive because they provide a level of precision that is necessary for machining, but is over-kill for woodworking.
There are number of advantages to using plastic 1-2-3 blocks in the wood shop instead of metal ones :
- They are more than precise enough for wood-working
- They are light and durable
- If you accidentally hit one with your saw blade it will not destroy the saw blade
- They can be designed with features useful to woodworking
A set (2) of low cost 1-2-3 blocks will cost you at least $20, but you can print a set for about $2. The dimensions of the ones I printed are within a few thousands of an inch (a few hundredths of a mm) of the nominal values - more than good enough for woodworking.
The design of these prints has been optimized for 3D printing (hence the diamond shaped holes), and to reduce filament use while retaining weight. In addition, there are screw mounting holes on all sides of the block so that the blocks can be attached to a piece of wood either temporarily or permanently with a small flat head screw.
Print Instructions
Print in PETG using the 3mf or gcode files provided; in general :
- 2 perimeters
- 10% rectilinear infill
These should also work in PLA, although I prefer PETG for use in the shop.
