Hybrid upgrade belt tensioners for Rat Rig V-Core 3/3.1

These are a remodel of Rat Rigs belt tensioners from the V-Core 4 hybrid printer.

These are specifically designed to work on a a V-Core 3 hybrid.

Unlike the V-Core 4 ones, these mount with T-nuts in the extrusions to allow:

Fitting without drilling the frame
Fitting without custom side plates
Fine height adjustment for perfect belt alignment.

Coffee fund
I except no kick backs or royalties from third party companies such as Funssor who manufacture stuff I model and post on Printables.

If you decide to make a donation to my coffee fund (which keeps me up late at night doing more of this stuff) I would appreciate it. There is absolutely no obligation for you to do this. My PayPal account is [email protected]

Please remember to post feed back as it is always valuable to me for future iterations.

Many thanks.
