3D printer parts and accessories by brand

Guides

• Belts, tension and layer shifts
  Ringing, wavy walls and prints that jump halfway through are usually mechanical. How to tension a belt by feel, and what else causes a shifted layer.
• Build surfaces compared: PEI, glass and textured plates
  Smooth PEI, textured PEI, glass and the rest — what each is actually good at, which filaments they fight with, and when a worn sheet is your real problem.
• Calibration tools: calipers, gauges and what you actually need
  One tool does most of the work and costs about a tenner. What digital calipers are for, and which other measuring kit is worth owning.
• Finishing tools: deburring, sanding and cleanup
  A handful of cheap tools turn a rough print into a finished part. What to buy first, the right sandpaper progression, and why wet sanding beats dry.
