Chain holders for tevo tarantula

I have done some brackets for my tevo tarantula to hold a x-chain and Y-chain.

First of all i have to thank eiPionezero for doing the chain links i have used:

X-chain:
There are 2 files "chain holder 4020" and "x spider tensioner". X spider tensioner is a chain holder but also a x belt tensioner. You will need the small part of the x tensioner:

"Chain holder 4020" is for attaching to 4020 profile, so you will need 2 tnuts.
I have tested this ones:

Y-chain:
There are 3 files: "vertical chain holder" that i have screwed to the wood base, "bed chain bracket chain up" (the one i have used for bed connector), and "bed chain bracket down" (not tested).
Difference between UP and DOWN parts are the windows size to be able to press the connector clip when you flip 180º the connector case.

I think the more neat way
