G-EDM Gapstorm Portal
The new G-EDM Portal is CNC machined from 20mm Aluminum and builds the basis for a solid XY wire EDM machine.
The add-to-cart button defaults to 3D printing and I haven't figured out how to change that yet. Please use this link to order the portal:

It is designed for long HGH20HA blocks on the Y axis. One block per side.
It has a 3:1 pulley reduction that increases the torque of the used Nema17 1.68A Motor heavily.
Note: The technical drawing is included for those who want to order it with all the threads done.
A real BOM to build the portal is not made yet but the core parts are:
1x HGR20 Linear Rail; 300mm length
1x HGH20CA Linear block
2x HGH20HA Linear blocks (Rails for y not included here)
1x SFU 1605 Ballscrew set with Ballnuthousing, BF/BK Bearing blocks; 400mm length
1x GT2 Pulley: 60T; 10mm Bore; 10mm belt width
1x GT2 Pulley: 20T; 5mm Bore, 10mm Belt width
1x GT2 closed belt: 234mm length; 177T
2x Ballbearing 8mm ID x 22mm OD (Used to tension the belt; washer between the bearing required)
1x M8 T-Nut for Slot8 (Note that it has to be a specific one with 16mm width and 6mm height; see image)
1x M8x55 Screw
1x 1.68A Nema17
And more screws. Please take a look at the freecad file to get thze exact screws needed. The downloadlink to the projects google drive is shared on the github page.
This type of T-Nut is needed:
