ZimaBoard Modular Rack Sled Remix - PCIe, Tool-free SSD, & other minor tweaks

I have not been particularly happy with the Zimaboard mounting options out there until finding @MartinRowan's excellent modular 1U system.

This remix was done to suit my specific needs, but I feel that some may be of use & worth sharing.

I specifically remixed the “ZimaBoard Sled (2 Drives)(large).stl” file from @MartinRowan.  So keep in mind that this ALREADY exceeds the 1U height.

• SSD/HDD Slots are tool-free
  • Snaps held at least through the 6 or so tests I did with various SSDs and 15mm drives
    • No, 15mm drives cannot be installed with either the Zimaboard or the PCIe card
• ZimaBoard mounts with the stock screws
  • Do not include any of the acrylic spacer plates, they are not necessary
  • Maybe this was fine on the other sleds, but I had trouble fitting things with the stock screws in the original
  • Also cleaned up the screw holes as I has issues printing the originals
• PCIe Block downsized
  • The PCIe Block interfered with some of my cards as it was too deep, overall.  This version is slimmed down and separated.
  • I've also included a version with holes for the Ableconn PEXM2-130 card.
  • If you want to do your own cutouts, I found a 3mm to 3.1mm hole stretching from the top to bottom of the block (~9.773mm) at a -5 degree angle lets me use standard M3 and longer M2.5 screws to mount the PCIe cards.
    • At 3.1mm, use a -6 or -7 degree angle.  -5 was a little loose
• Tail End of Board Tapers Up
  • I found especially on the 2W sleds that they could sag and catch on the end of the holder, so I added a little taper upward at a 45 degree angle
• Extended Sled
  • The set includes a slightly longer sled with an extended tail (about 7.5mm) to provide a little extra surface area for mounting other hardware
  • Specifically, I wanted a space to mount a fan header expansion board
    • ThreeBulls PWM Fan Hub
    • Amazon Product: B07M5P7VHG

Print settings

• 0.2 mm layer height
• 0.4mm nozzle (is what I tested with; 0.6 should work fine)
• No supports
• 3 walls
• 15% infill
• Printed in PLA, but I have cooling fans on this - print with something tougher

I've included STEP files for all of the included STLs.  I am not sharing the Fusion file at the moment, because I cannot bring myself to inflict that mush pain on anyone else.  Shoot me a message if you really want to suffer THAT terribly…
