The following is sort of related to my next S.E.5a build, but not specific to it. I have wanted to make a modelling stand to make things easier when decaling, painting etc. After looking into my options and cost, I decided that I could easily design my own and find a business to CNC Router or Laser cut it for me. Mt original material of choice was plywood, but it became very clear that the complexity of making something and putting it together with ply was too hard/expensive.
The local business I discovered suggested an alternative, acrylic sheet. As they have a laser cutter the following and with materials and hardware came to roughly 1/3 of the cost of the retail version. And the best part as it can hold a 1/48 aircraft and I would hazard a guess could go to 1/24 if needed for Mono, Bi and Triplane.
