4040 Extrusion Linear Carriage

thingiverse

I bought some 4040 extrusion for a cnc build project and realised there is lots of things out there for 2020 but little for 4040. So I designed and built my own carriage. It is modular in design and uses the same clamp arrangement as used in my 4040 t-nut so you can just plug them in etc. <a href="https://www.thingiverse.com/thing:2513895">https://www.thingiverse.com/thing:2513895</a> It is designed for linear motion on extrusion and uses both sides so is not v-slot etc. I have included the tinkercad object file as this was made before I started using OpenSCAD. Hope it helps people to remix <o:p> </o:p> Features<o:p></o:p> <o:p> </o:p> Modular so split the stl and print what you need :-) Hardware Needed<o:p></o:p> For Each Full Carriage Mount<o:p></o:p> --6 x M5 x 30mm Bolts --18 x M5 Nuts. Used as spacers but you could use washers or springs --6 x Wheels. I used 22mm OD by 7mm Width bearing type with 5mm hole Other Notes.<o:p></o:p> --You may need to tweak the scale etc depending on the accuiracy of your printer and your exact extrusion.
