Sand/Rock Filling Equatorial Mount Counter Weight

thingiverse

This container serves as a metal counterweight substitute, particularly useful for extended travel where luggage weight reduction is crucial. The container's volume stands at approximately 1 liter. When filled to capacity with sand and rock, its total weight comes in around 2kg. The central hole diameter measures 19mm, making it an ideal fit for Takahashi EM-11 equatorial mounts. Printing in PLA material is highly recommended. A 25% infill is typically sufficient for most cases, while a lower infill of 10-20% can significantly reduce material usage and production time without compromising structural integrity. Additional materials required include: * M6x30 to M6x50 screw: one full-threaded unit * M6 flange nut: one piece * Hex key for the M6 screw * M4x10 screw: three units * Sealant (optional, at user's discretion) Assembly instructions follow: 1. Post-print cleanup involves removing ooze and smoothing out fillets on all parts. 2. Remove support material from within the lock screw area. 3. Insert the M6 flange nut into its designated cutout and adjust as necessary. 4. Thread in the locking screw, then clean up any excess material from the hole. 5. Seal the open cutout with sealant if filling the container with wet materials like mud or stones is planned (e.g., RTV silicone). 6. Use an M4 threading tap to thread the three holes on the cover. 7. Secure the three M4 screws in place.
