What it is
A modular mounting set for an EQ5 pier extension (geometry/dimensions per the included drawing).
It lets you mount power + control electronics directly onto the pier extension, keeping the setup compact and reducing cable mess.
Included modules
Each module is a dedicated bracket for one item:
MINIX mini PC holder (chonky one with passive cooling) - tested with MINIX Z100
12V 10A (120W) PSU holder by Movano - also likely fits other generic/chinese PSUs with 66×40 mm cross‑section and any length limited by pier length
OnStep V5 Pro holder - for the Terrans Industry OnStep V5 Pro; fits SV241 as well (and probably AsiAir)
DC power splitter / distribution holder - for standard barrel connectors: 2.1/5.5 and 2.5/5.5mm
Cable routing guide - simple strain relief / cable management at the pier
You only need to print the modules you need.
Clamping concept
Every module consists of two printed halves that clamp around pair of vertical pier tubes. See photos for reference.
The halves are bolted together using:
M4x25mm screws
M4 nyloc nuts (chosen specifically so the bracket does not loosen under vibrations/long term usage)
Because the clamp grabs two tubes at once, the mounts are stable and can be repositioned by loosening and sliding.
Nut pockets (intentional tight fit)
The M4 nut traps are deliberately tight - once pressed in, the nuts stay in place. This reduces the chance of losing nuts while installing or sliding the mounts on the pier
Easiest way to seat the nuts:
1. Place the M4 nyloc nut over the nut pocket.
2. Insert an M4×25 screw from the opposite side.
3. Tighten the screw until the nut is pulled fully into the pocket and sits flush.
This is the same practical "pull-in" technique commonly used in Prusa-style assemblies.
Compatibility note
Designed for an alluminium EQ5 pier extension with four vertical tubes according to the attached dimension drawing.
If your pier extension has different tube diameter/spacing, you may need to adjust the model or scale accordingly.
