Boost Me (for free) Could I help you with this device? Then I would be very happy about a boost from you! Boost Rotary Clamping Aid for Christmas Tree Ornaments (20–100 mm) This 3D-printed clamping aid was specially developed for the safe and reproducible engraving of Christmas tree ornaments in a rotary laser fixture The goal was to fix sensitive glass balls without tension, centered, and twist-proof – without clamps, without pressure marks, and without risk from the laser 🔧 Functional Principle The ball rests at the top of the holder and is gently pulled downwards by an internally guided piston. The piston is pre-tensioned by an elastic band at the bottom, creating an even and soft pulling force The piston is guided securely within a housing By pulling the piston towards the ball, the pre-tension can be released → quick ball change The elastic band is located outside the laser area and is thermally safe, it is guided through the cross at the bottom of the piston, admittedly, it's a bit fiddly but you can easily thread the elastic band through with the tip of a paperclip! 📏 Compatibility Suitable for ball diameters from approx. 20 mm to 100 mm (depending on how high your rotary is) Works with most rotary axes (roller or chuck) ✅ Advantages Tension-free fixation of sensitive glass balls Self-centering and reproducible No twisting during engraving Quick change between different ball sizes No metal or spring parts in the laser area 🖨️ Print Recommendations Material: PLA, PETG or ABS Support only necessary for the piston with hook Clean dimensional accuracy recommended for the hexagonal guide Please remove the support from the hook only when the part has cooled down and with CAUTION! It was tested on the Xtool Rotary and found to be good! ⚠️ Note Please remove the support from the hook only when the part has cooled down and with CAUTION, as the hook could otherwise break! 🛠️ How to use Prepare the clamping aid Make sure the piston slides freely in the hexagonal housing and the elastic band is correctly hooked at the bottom Release the piston Pull the piston upwards towards the ball to release the pre-tension Insert the Christmas tree ornament Place the ball into the holder from above. The ball rests self-centringly in the support Pre-tension the ball Slowly release the piston. The elastic band pulls the piston down, creating a gentle, even pre-tension that holds the ball securely – without pressure or clamping Insert the clamping aid into the rotary Place the complete unit in your rotary axis (roller or chuck) and align it parallel to the laser axis Focus the laser Set the laser focus on the surface of the ball. Check if the ball rotates freely and evenly Start engraving Start the engraving as usual. The ball remains centered and twist-proof in position Remove the ball After engraving, pull the piston upwards again, remove the ball – done
