🛠 Required Hardware:
• M3 locknuts (4mm height)
• 8mm countersunk M3 machine screws, 
• 40mm countersunk M3 machine screw, 
• v-groove bearings (3x12x4 mm). 
• Optional: m3 sleeve nut https://www.rvspaleis.nl/moeren/hulsmoeren/verzonken-binnenzeskant/9062-2-3_1- For stacked slide configurations
 

💡 Installation & Stacking Tips:

• Standard Installation: Follow the assembly video for detailed instructions.
• Stacking Multiple Slides: For better stability when stacking slides, replace the standard M3 locknut with an M3 sleeve nut.
  1. Drill a 4.5mm hole in the Misumi slide at the desired mounting point.
  2. Insert the sleeve nut from the opposite side.
  3. Secure the insert using an 8mm M3 countersunk screw.
  4. Apply Loctite (e.g., Loctite 243) to the screw threads to prevent loosening due to vibration

⚙️ Recommended Print Settings:

• Material: PETG, PLA+, ASA, or ABS (PETG recommended for a good balance of strength and ease of printing)
• Layer Height: 0.2mm
• Infill: Gyroid 40-60% (or higher for maximum strength, e.g., for the 20kg lift scenario)
• Wall Count/Perimeters: 3-4
• Orientation: Print with the largest flat face on the build plate for best results.
• Supports are not necessary
