I know there are quite a few designs, variations, versions … after countless modifications I’m sharing my clamp design for mounting a Flipsky 65121 (or similar) or a 63100 to a Gong v2 mast: simple yet strong. I call it the “10 ct clamp” because an important part of it is a coin: a 10 ct Euro, a Dime or anything around 20 x 2 mm will fit. It withstands all the force, the plastic just holds everything in place.

Apart from a 3d printer, you will also need (63100):

- 4x rods length 140 x 4 mm
- 4x M4 nuts + 4x M4 self-locking nuts
- 2 screws for wood / self drilling, 12 x 2 mm
- a clamp made of metal sheet

Or analogue for 651xx:

- 4x rods length 140 x 5 mm
- 4x M5 nuts + 4x M5 self-locking nuts
- 2 screws for wood / self drilling, 12 x 2 mm
- a clamp made of metal sheet

All stainless steel of course. I’ll let the images speak for themselfs. If you have questions, let me know. Here ([63100](https://cults3d.com/en/3d-model/various/10ct-flipsky-63100-gong-v2-mast-clamp-for-efoil)) and here ([651xx](https://cults3d.com/en/3d-model/various/10ct-flipsky-651xx-gong-v2-mast-clamp-for-efoil)) are the 3d-files along with detailed description how to mount. I have used 0.7 mm metal sheet, this is more than strong enough and still can be cut, drilled and bent as needed by hand.

63100:

Just what I’ve been looking for my planned 63100 build! As you said there are a few designs, but the clamping with the coin is a clever idea to get things very tight without risking breaking the print, and keeping print size low. Another great feature is ample room for cabling and connectors. Well done!
