Figured as much.
Don't suppose you have the specs on the panels you're using for the T1? As in the hole sizing, spacing, and thickness? I've been looking around for similar plain perforated sheet metals on eBay but I can't find anything quite right. Either holes are too big or the mesh is too fine.
The mesh is custom, 1.1mm diameter vents with 1.8mm spacing on 1mm metal.
You are not going to find T1 mesh on the market, because this spec make it very expensive, even more than aluminum + anodizing, for economic reasons, most factories will not make it.
You can make mesh *economically in 2 ways:
1) chemical process (<0.5mm thick steel)
2) punching (holes diameter 1.5x thickness)
You want be ~ 1mm diameter holes for dust filtering purpose. T1's 1.1mm holes on 1mm thick steel requires 1) custom metal, 2) custom tooling and 3) custom oil lubricant.
If you are missing any of the 3 ingredients list above, you will get a panel that is severely warped, surface damaged beyond recognition or use 0.7mm thick metal, which will have stiffness / flex issues. I know because we tried and failed many times.
Afiak, there is no mesh on the market with similar combination of:
1) vent hole diameter vs thickness ratio
2) ventilation density vs. surface area ratio (without having to emboss to add strength)
3) over strength & flex
How feesible would it be to get NCase side panels using that same style of metal mesh?
Too much my plate atm, so not in the plans.
This is also why making it for the M1 is more complicated.
The surface area of M1 Side Panel is more than T1 Side Panel. Once you increase surface area, you will get more Flex on the Mesh Side Panel, which you will need to compensate by either 1) emboss / flanging, 2) changing mesh spec or combination of both.
I just don't have time to do it right atm.
