Description The 1X2 is a Reprap class 3D-printer that can be built with access to only a drill-press and hand-saw. All the parts can be made with one-dimensional tools and straight cuts. Even with these limited requirements, it is designed to be easy to build and have a full set of features.

- It has a printable area greater than all of its parts(including the rods).
- Dual-head extruder and plotter(w/ hot and cold separation).
- Simultaneous extrusion and plotting.
- Quick-change plotter head.
- Extremely narrow x-carriage design.
- It uses only 608 bearings.
- It uses only 5/16" bolts.
- It uses all 1-unit length rods.
- It uses all DIY belts.
- Uses all DIY drive pulleys.
- Uses all DIY couplers.
- Full conveyor-belt y-axis(reduced parts, high accuracy, low weight, automated ejection, large build area).
- Adjustable conveyor belt tension with bed height.
- Conveyor-belt goes to both edges of the machine for end-to-end chaining of machines.
- Hand-crank for conveyor belt.
- A single block is capable of building all frame vertex points.
- A single extended block is used for Nema17 motor mounts, 608 bearing axle supports and pillow-blocks.
- The 5/16" holes fit both 8mm & 5/16" hardware.
- Works with variable lengths. The design is not length specific, so you can build a range of
- machine sizes, from full size to compact with the same pieces.
- The frame is chainable, you can build a linked multiple segment Longcat machine.
- It uses only 1"x2" wood for all parts.
- It uses a 35/77 system, where all the parts are either 35mm or 77mm in length. The parts for the entire system can be cut to length in two fixture setup runs(with a few exceptions).
- All cuts are 1-dimensional 90 degrees.
- Adjustable tension with no pulleys or pusher blocks.
- The "scoop" extruder uses the PTFE tube itself as the "idle pulley"
- It uses the Makerbot Mk5 nozzle and hot-end tube.
- Makergear style geared stepper.
- Raysyu drive gear.
- A Nophead style heater block.
Plotter Head: This single pivot floating head plotter arm works consistently over a very wide range of surfaces. The servo actuation provides fast on-off movements. The entire plotter arm and servo can be removed or switched with another pen without taking the pen out of position. The large 5/16" holding nut uses low force and acts as a knob that can be easily spun on/off by hand. The band clamp pen holder can hold just about any pen sized tool.
