LowRider 3 CNC - three remixes of Rail Blocks (18.1 mm, 23.4 mm, and 25.4 mm) for Unistrut or 1-½" Aluminum Square Tube

Note: There is an updated listing with a newer version of this remix: https://www.printables.com/model/415298-lowrider-3-cnc-three-remixes-of-rail-blocks-181-mm 

Also note: Several of my designs for my CNC plasma rig are available here for free.

I had previously created a couple of different remixes of the LowRider v3 rail blocks (Y rail mounts), one for my unistrut-based LR3 for a router (#1 — 23.4 mm), and another one for my 1-½" aluminum square tube-based LR3 for plasma (#2 — 18.1 mm).

These are my third remix of the rail blocks. The only difference between v2 and v3 remixes (of the 18.1 mm block) is that the v3 has a screw slot instead of a screw hole, so it offers some adjustability. I kept that feature in the 23.4 mm and 25.4 mm options of the “third remix.”

These all have a narrower footprint than the original rail blocks, for fitting onto either unistrut or 1-½" Aluminum Square Tube.

I used the third-phase remix for the 1-½" aluminum square tube of my LowRider v3-based plasma rig. However, as mentioned, these rail bocks could also be used for Unistrut-based LowRider 3's.

Tubing sizes…

• “rail-block-REMIX-3-18p1.stl”  is for 18.1 mm OD tubing 
• “rail-block-REMIX-3-23p4.stl” is for 23.4 mm OD tubing
• “rail-block-REMIX-3-25p4.stl” is for 25.4 mm OD tubing 

Print info:

• Print as oriented
• Print without supports
• You will want these printed strong. I printed with 0.6 mm nozzle, with 4x4x4 (4 walls on both top, bottom, and perimeter walls) and 70% infill. The same settings could work for 0.4 nozzle. As soon you start tightening screws into them you will be glad you made them strong.
