X-Carriage with holes for energy chain and light

1st STL: Added additional space at the top with two holes to mount a energy chain (mine is https://de.aliexpress.com/item/Free-Shipping-Best-price-10-x-10mm-L1000mm-Cable-Drag-Chain-Wire-Carrier-with-end-connectors/32735832922.html), meanwhile I tested a 7x7 chain which got the same screw distance.)

2nd STL: as the 1st one, with additional space at the buttom, to mount a led plate, mounted with straps: https://www.banggood.com/1_8W-12led-COB-LED-Chip-130mA-WhiteWarm-White-For-DIY-DC-12V-p-95
