Vibration tumbler - Vibratory tumbler machine frame(needs non-printed parts)

Here's a step-by-step guide to building a DIY rock tumbler: Materials needed: * A 3D printer * A soldering iron and solder * Wire * Optional: JST connectors or similar for easy power supply removal * Glue clamp or other means of securing the tumbler * High-density foam mat or similar to absorb vibration (optional) * Rubber mats or similar can also work * Toggle switch (optional) * Electrician's tape or heat shrink tubing for protecting solder joints Instructions: 1. Print the frame: All parts can be printed at 20% infill except for the threaded rods, which should be printed at 100%. 2. Attach the motor stop to your motor: This prevents the motor from falling through the motor hole. A snug fit is recommended, and a bit of glue may be necessary. 3. Screw in the distancers: These go into the slots on the bottom frame part and do not need to be glued. 4. Attach the threaded rods and springs: This can be a bit tricky. 5. Put bolts in the tumbler tub blocks and glue them onto the top frame: Two-part epoxy or an ultra-strong glue is suggested. 6. Put the motor in the motor hole and arrange the wires: Optionally, tape them down. 7. Make holes in your tub to fit the 4 bolts and one hole for the bolt that will hold your cone: Build a cone using a plastic syringe, nut, and electrician's tape, or get creative. 8. Put the tub on the 4 bolts, attach the nuts, and make a water-tight seal: Use silicone caulk or hot glue (but be careful with hot glue). 9. Let the caulk set if you used it to make a watertight seal. 10. Test your tub with water to ensure it's watertight. 11. OPTIONAL: Add soldering sponges or craft foam between the tub and blocks to quiet the tumbler. 12. Attach all electronics as desired: A simple working circuit is connecting a power source directly to the motor wires. Consider adding a toggle switch and stepping down the voltage with a buck converter (available on Amazon or eBay). 13. OPTIONAL: Place the tumbler on a craft foam mat to quiet it down. 14. Put a clamp on the bottom of the frame to keep the tumbler in place. 15. Add tumbling medium, lubricant/solution, and turn on your tumbler. Tips: * Use 100% infill for threaded rods due to their small size. * Consider using a buck converter to step down voltage for better motor control. * Use electrician's tape or heat shrink tubing to protect solder joints. * Add craft foam mat or similar to absorb vibration and quiet the tumbler. Note: This guide assumes you have basic knowledge of 3D printing, electronics, and mechanical assembly. If you're new to these areas, it's recommended to seek guidance from more experienced individuals.
