Braucht es keine Dichtung für die Trommel? Ist der Deckel, so wie er gezeichnet ist, wirklich Wasserdicht?

Doesn't it need a seal for the drum? Is the lid, as it is drawn, really watertight

can we see results? do you have video of it in action? so curious!

<h3>Basic Assembly Instructions for DIY Rotary Tumbler Polisher</h3><h4>1. Required Components</h4>The assembly consists of 3D-printed parts, bearings, fasteners, an electric motor, and wiring components. The 3D-printed parts are primarily made of PETG-CF and TPU, while the fasteners and electrical components ensure mechanical stability and functionality. The body and sides can be printed in PLA but the rollers and the drum should be of a more durable material. I was very pleased with the PETG-CF. I also have a rather dense infill and this could be reduced but I like how sturdy and substantial the machine is.<h2>Step 1: Assemble the Frame &amp; Electrical Box</h2>Parts Required:<ul><li>Left Side Panel (PETG)</li><li>Right Side Panel (PETG)</li><li>Electrical Box (PETG)</li><li>M5 Brass Inserts D7 (x10)</li><li>M5 Hex 25 Screws (x4)</li><li>M5 Hex 10 Screws (x6)</li></ul><h3>Instructions:</h3><ol><li>Insert the M5 brass inserts into the mounting holes of the side panels using a soldering iron or a heat press.</li><li>Attach the electrical box to the right side panel using M5 hex screws (25mm and 10mm as required).</li><li>Secure the left and right side panels together, ensuring proper alignment with mounting points.</li><li>Keep the left side removable for servicing the belt and tensioner later.</li><li>Note: The tolerances for these parts are very tight to ensure a snug and solid connection, especially between the right side and the electrical box. Some users may need to lightly hand-sand the fitting surfaces for optimal alignment.</li></ol><h2>Step 2: Assemble and Install the Rollers</h2>Parts Required:<ul><li>Roller 1 (PETG-CF)</li><li>Roller 2 (PETG-CF)</li><li>608 Bearings (x5)</li><li>M3 Brass Inserts D9 (x4)</li><li>M3 Hex 5 Screws (x4)</li></ul><h3>Instructions:</h3><ol><li>Super Glue the Rollers Together – The rollers consist of multiple 3D-printed sections that must be super glued to ensure solid and true rotation, preventing wobble.</li><li>Press-fit 608 bearings into both ends of each roller. The tolerances are very tight, so ensure alignment is correct before pressing them in. Light sanding may be necessary if the fit is too tight.</li><li>Use M3 brass inserts and M3 Hex 5 screws to secure the rollers into the side panels.</li><li>Ensure the rollers rotate freely before moving to the next step.</li></ol><h2>Step 3: Install the Tumbler Drum</h2>Parts Required:<ul><li>Tumbler Drum (PETG-CF)</li><li>TPU Belt (Drive System)</li></ul><h3>Instructions:</h3><ol><li>Place the tumbler drum on top of the rollers.</li><li>Ensure the rotation is smooth without excessive resistance.</li><li>Install the TPU belt around the motor pulley and drive roller to ensure proper motion transfer.</li></ol><h2>Step 4: Install the Motor &amp; Toolless Belt Tensioner</h2>Parts Required:<ul><li>12V DC Motor (4mm Shaft)</li><li>M5 Hex Screws</li><li>TPU Belt</li><li>Small Pegs (3D Printed, PETG-CF)</li></ul><h3>Instructions:</h3><ol><li>Mount the 12V DC motor inside the electrical box, ensuring the shaft aligns with the roller.</li><li>Attach the TPU belt to the motor pulley and drive roller.</li><li>Insert the small pegs into the square holes along the rails of the tensioner system. These pegs allow the tensioner to slide back and forth but also securely lock in place without tools.</li><li>Adjust the belt tension by sliding the tensioner back and forth along the rails, ensuring proper drive belt tightness.</li><li>The left panel remains removable, allowing easy access to the belt and tensioner for future adjustments or maintenance.</li><li>Note: The tolerances for the tensioner rails are tight to ensure stability, so light sanding may be needed to ensure smooth sliding action.</li></ol><h2>Step 5: Wire the Electronics</h2>Parts Required:<ul><li>SPST Round Rocker Switch (with LED)</li><li>12V DC Power Supply</li><li>Wire &amp; Connectors</li></ul><h3>Instructions:</h3><ol><li>Follow the wiring diagram below for proper connections.</li><li>Connect the motor leads to the switch (positive terminal) and ground.</li><li>Wire the 12V DC power supply to the switch and motor.</li><li>Use wire connectors to secure all electrical connections.</li><li>Test the power switch to ensure the tumbler rotates properly.</li></ol><h3>See the wiring diagram in the images for electrical connection.</h3><h2>Step 6: Final Assembly &amp; Testing</h2><ol><li>Secure the left side panel after confirming belt tension.</li><li>Run the tumbler without media to check for smooth operation.</li><li>Load with polishing media (walnut shells, corn cob, or ceramic) and test with small parts.</li></ol><h2>Notes &amp; Adjustments</h2><ul><li>The tool-less belt tensioner system allows for quick and easy belt tension adjustments without the need for additional tools.</li><li>Super gluing the rollers is critical to maintaining a smooth, stable, and wobble-free rotation.</li><li>Tolerances are intentionally tight for the bearings, tensioner, and connection of the right side to the electrical box. If parts do not fit easily, light hand sanding may be necessary to achieve a proper fit.</li><li>If noise or excessive vibration occurs, recheck roller alignment, motor mount stability, and belt tension.</li><li>Additional modifications can be made to add speed control, alternative power sources, or a larger drum.</li></ul><h2>Encouraging Remixes!</h2>This design allows for customization and modifications. If you improve the design (e.g., add variable speed control, upgrade to a different motor, or change drum sizes), share your version—I’d love to see what others come up with!
