Thank you for viewing. This is an adapter "for 12 fins" to display a BONBONERO on a ZEROPOD38, etc. This model is compatible with 12-fin models, such as the NATAL DESIGN BONBONERO. You can fix it by inserting the longer fins of the BONBONERO into the grooves of the adapter and tightening the string. Also, if you use this with the "Custom 38-light Parts for BONBONERO, for 12 fins" sold here, you can use the screw adapter with two custom fins added to the normal BONBONERO. (Images 6-8) *Images 3-8 are installation images and are made of PLA resin of the same shape. *Be sure to use the ring parts that come with the BONBONERO. *Cannot be used with versions where all fins are short, such as BONBONERO meets zero_cap. *A Hakuba camera screw adapter H-SA8 is attached to the bottom of the adapter. *Removing the adapter will create a 3/8 screw hole, but we do not recommend using it in that state due to strength. *We do not plan to produce M8 because the hole is large and it is difficult to make it shorter. *This product is 3D printed and handmade, so there may be slight individual differences. *We are not responsible for any damage or malfunction of the BONBONERO or ZERO TORCHSTAND, etc., connected to this product. *Specifications and prices are subject to change. *Please check the profile section if you wish to change the color of the product. *If you wish to purchase multiple items, please contact us in the comment section.
