You need two M3x25 and two M3 Nuts.
Print the holder and Thumbscrew twice.
Just add a pause after the hex section on the thumbscrews, add a M3 Nut to your print and resume.
The M3 bolts I glued into the holders.
Fit my Gens Ace 6570mah hardcase as well as my Gens Ace 5000mah Bashing. I mount them with the kabels to the outside.
The author marked this model as their own original creation.
