Ender 5 adjustable bed support struts

Inspired by the many existing ender 5 bed support struts, but with the following improvements:
**Adjustable.** Turn the bolts until the bed support itself is vertical. Then fine-tune the bed.
**Heavily reduced use of filament/printing time.** This model uses about 35g of plastic and can probably be printed in less than an hour. It took me about 2 hours but I'm still learning PETG ;)
**Not reliant on a specific kind of plastic.** I printed it in PETG, but I'm sure PLA will also do fine.
**Stronger.** Those metal rods will warp way less than metal over time, I think.
**Printable with minimal support.** Struts A and B don't need any support. C can be printed with the two nozzles pointing up, with minimal supports.


You'll need the follow additional items. I found them at the local hardware store for less than 2euro:
2x M4 threaded rods, length: 210mm.
4x M4 spacer. Mine were 12mm in diameter.
4x M4 long hex nuts
