Drawer for the ZIMO S1C riser component

Since the big shot hasn't released the riser drawer files, I've designed one myself to fit the ZIMO S1C riser component. I'll continue to update the side mounts later (depending on my free time, it's very busy after the new year)

I made several adjustments in the middle, and finally found that I used filaments from two different brands when printing, the shrinkage rates were different and the two sides didn't match up, creating a large gap in the riser component. Therefore, I made three configurations:

1. 273.8mm in length, which can be inserted to the bottom. Because it's larger than the A1P1 build plate, it needs to be printed sideways, 31.2mm in height for a snug fit;

2. 250mm in length, which can be printed flat on the A1P1 build plate without supports, also 31.2mm in height;

3. 250mm in length and 31mm in height, leaving some room for printing errors. This one won't be held by the bottom slide rails, but it should still fit without issue.
