I designed this bottelholder because my first one is broken and I want a bigger one anyway.
The first Version ist for bigger bottels up to 70mm diameter and is fastened with straps or velcro strips.
If you like I will add a version for other sizes and with other attachement typs (cable tires and screws)
Added v2 to fix it with screws and addes the STEP modell so you can make holes at the Position you like
improved and added v2 Belt
