Mod for 10x11 dragchain with openings (https://www.aliexpress.com/item/32214281467.html).
Original mount didn't fit on my Vcore3.1 anyway (insufficient clearance when Z=0), I had to mod it a little bit more than just adjusting holes for dragchain.
It is mod, but especially in case of upper part, I was unable to mod it from STL so I redrawed it from scratch (that's why it differs a bit more than it has to be). Plus added protection wall for wires (just in case).
BOM:
6x Heat inserts (M3x5x4)
6x M3 countersink screws
2x M6 T-nuts for 3030 ("V-core3 extra parts bag" will have it)
2x M6x12 counterbore screws (same as with T-nuts)
10x11 dragchain
The author remixed this model.
