Rack Mount for Beelink S12 Pro

Why another rack mount for the Beelink?

TLDR: The others were just too flimsy for me.  Modeling my own also gets me the features I want.

The Beelink mini PC is ~40mm tall, which leaves only 4mm spare inside the thin 1U rack slot we all want to put this into.  With no side fastening options available, this is a challenge.  The other models I looked at just left too much on the table.  They may work, but things slip and accidents happen.  I want strong.

The choices I made:

• limited front access.  This model has a window to access the front panel, rather than an opening that allows the unit to slide out.  This is much stronger.
• bottom tray only.  This allocates all 4mm for support.
• thickness for layers.  Layer adhesion is the achilles heel of 3d printing, but not so much if surface area is large.  The design uses large tapered geometry.
• one piece print.  The model is split in half because our printers aren't big, but I did consider splitting up the model more to optimize print direction, but this design doesn't need it.
• ribs.  Steel patch panels have ribs.  Most other models don't do this and flex like spaghetti.  I don't get it, they are so easy to add to 3d models.  Mine have them.
• M4 threaded inserts: Most other models use hex nuts, but you need:
  • rear access.
  • to offset the nuts further into the model which doesn't make for strong placement.

And some touches:

• Beelink is designed to be screwed into a VESA mount, and comes with the screws.  You can fasten Beelink to my model with the same screws.
• There are also stops in the back preventing Beelink from being pushed out.
• My design adds strain relief for the power cord: a cord grip with integrated zip tie mounts.  So accidentally pulling out the power cord is less likely.

Before you print:

• Check the size of your M4 inserts.  The holes in the model are 5.1mm.  Modify > Change Parameters in Fusion 360.
