Contents:

• MGN12 rail guide and MGN9 rail guide:
  For centering the rails on the aluminum profile before screwing.
  
  

• Extruder PTFE length cutter:
  Helper for shortening the correct length of the 44.8 mm PTFE tube between the cooler and the BMG extruder.
  
  

• Hotbed screw adjust:
  Helper for initial manual bed tilt adjustment using a screwdriver (using between magnetic base and bottom metal support plate).
  
  

• Calib EL 140x100mm: 
  Calibration EL, for measuring printed right angles (to compensate for bed skew) and print lengths (for calibration: steps per mm), is useful when printing larger models.
  
  Note on Length Calibration (Steps per mm): Keep in mind that multiple factors can affect dimensional accuracy, not just incorrect steps per mm settings.
   
  For example: I observed small variations in the expansion and contraction of the same PLA filament when printing in summer vs winter.
  
  My recommendation is to follow these guidelines:
   

  • Length difference ≤ 0.2mm → Do not calibrate steps per mm

  • Length difference 0.2mm – 0.4mm → Consider calibrating steps per mm

  • Length difference ≥ 0.4mm → Calibrate steps per mm

• Kit Scraper Mini Set:
  Helper for applying putty when repairing plywood boards before painting.
  
  

• ASA_anti-warping_triangles:
  For printing from ASA you can use anti-warping triangles: Open triangles in the slicer, split them into single objects, and move them to the corners / edges you need to reinforce, place them with an ~ 2 mm offset from the object and use 4 mm brim on everything. Remove them with small cutting pliers.
  
  Anti-warping triangles work on the principle that they concentrate their shrinkage into one point, which is also a corner of the printed object and where the shrinkage forces on both sides of the equation cancel out.
