Summary

I created an entire range of connectors, designed to join 20mm electrical conduit to form frameworks for garden trellises, and frames for frost covers and netting. Use the link below to have a look.

This PROTOTYPE adaptor ONLY works with my 10-way connector, found here:

https://www.thingiverse.com/thing:6182651

If there's any interest/need to make an adaptor for the other connectors in my series, please let me know.

WHAT THIS IS FOR:

If you're looking to add some support to your 20mm conduit frame, especially if you're considering adding vertical supports in the middle, then I have built this adaptor to fit a "50mm" (Despite it having a 56mm outside diameter) PVC pipe as a viable vertical shaft/stem.

The reason I chose 50mm PVC piping, is because it's a common garden framing material that is freely available, weatherproof, and MUCH more rigid than the 20mm conduit. Allowing you to build an umbrella-like structure/dome.

You may want to install these into larger hoop houses/frames, just in case you have a hail storm, or snow, or other unexpected weight that needs management.

In Print Settings > Layers and Perimeters:

Set resolution/layer height to 0.1mm
Increased the number of "Vertical shells"/Perimeter layers to 8 or 10 (can't quite remember)
Enabled "Detect Bridging Perimeters"
Set seam position to "Aligned" (in advanced section)
Enabled "Fill gaps" (in advanced section)
Set Perimeter Generator to "Arachne"

In Print Settings > Infill:

Fill density 50%
Fill pattern: "Gyroid" (although you can use what you prefer)

Post-Printing

Using M4 Bolts to attach connector to the pipe adaptor

The 5mm holes in this adaptor line up with the holes in the 10 way connector. The holes are designed to use M4 (or 5/32") bolts, which are at least 80mm (3") long. This bolts the adaptor to the underside of the 10-way connector... all while going through any installed 20mm conduit ends, anchoring them as well. See my connector pages for instructions about the conduit side.

ATTACHING THE PVC 50MM PIPE: GLUE VS BOLTS,

If you are ARE gluing the PVC shaft to this adaptor, you can use all the M4 bolt holes as indicated.

If you are NOT gluing the PVC shaft to this adaptor, you're going to lose the use of TWO, M4 bolt holes since the M10 hole that anchors the 50mm PVC pipe would collide with those M4 bolts.

Sorry, like I said, it's a PROTOTYPE, and I haven't sorted it out yet.

In this case, I suggest using 10mm (3/8") theaded rod and some nuts, but you could use a longer bolt with similar diameter.
