The recommended minimal set of essential equipment for building the TV Prusa design is:

• A flat and level surface to build on¹
• 2 x 13 mm spanners
• a spanner/socket for the M3 nuts (5.5mm
• Allen keys (hex keys) at 1.5 mm, 2.5 mm and 3 mm
• Tri-square (aka try-square)
• Spirit level
• Feeler gauges (for nozzle height settings and leveling the bed)
• Soldering iron and solder - see soldering requirements and guidance
• Multimeter

Additional equipment which will probably be useful includes:

• Digital callipers
• Side-cutters for cutting filament
• Hammer
• Metric drill bits for cleaning out holes. I believe 3mm, 3.5mm, 4mm, 5mm and 7mm and 8mm are the set needed. A round file or rolled-up sandpaper is also useful for reaming out the tear drop bar clamps

¹ Both flat and level are important. If your build surface is not flat, your frame will wobble when placed on a real flat surface.

Tools Required

• A clear work area with good lighting, firm smooth surface and comfortable seating
• Soldering iron, if using a variable temperature controlled soldering station, set it to 400°C (or the correct temp for your solder type)
• Steel pan scrubber or other soldering iron tip cleaner
• Thick and fine solder
• Blu-Tack – to hold components while soldering (this tip copyright Michel :) )
• Desolder braid and/or pump – in case of solder bridges
• Long-nose pliers
• Side cutters with flat-back jaws for trimming legs clean to board – the clippings are sharp and fly all over the place unless you cover them with your hand. Beware your eyes
• Tweezers – for placing and holding the surface-mount resistors while soldering
• Anti static earthing strap
• An LED torch or other bright light source for – reading capacitor values
• Magnifier
• Resistor colour code chart and/or multimeter for identifying resistors
• A "Do Not Disturb" Sign
