Recumbent Bicycle Stationary Support

I have a recumbent trike and love using it in the Spring and Fall, but hate to see it just sitting idle when the weather doesn't cooperate.

The roller system I purchased to use it indoors was designed for a regular bicycle, so I needed to add a couple of supports for the front trike wheels to get the height right so I didn't feel like I was pedaling downhill all the time.

The challenge was to design them in sections that can be printed on my Tantillus RepRap printer bed that is 100mm x 100mm x 100mm.
