For LowRider v4: End Cap for 1" EMT (29.5 outside diameter)

OK, I made this revision of my end caps for 1" EMT, and I’m currently printing to try it out. 11 min print for me.

Note: For LR4 makers outside the US, supported tubing sizes include 30mm and 32mm outside diameter. For using this print with those sizes, scale it in your slicer.

For 30mm OD tubing, try scaling this print at 101.69%.
For 32mm OD tubing, try scaling this print at 108.47%

OK, I printed it, and tested in both “non bur” EMT, and “de-burred / blunted bur” EMT.

It fit snug and removable from the EMT with no bur, and tight and difficult to remove from the EMT that had a bur, but it worked in both.

I know this might not be the right thread to ask this in, but I can’t find a straight answer anywhere. Where do you get a 32mm OD EMT? Lowel’s and Home Depot have 1" 1/4 inside diameter EMT that’s 38.2 OD and it blows/breaks the braces apart. They do both carry a 32mm OD ridged pipe that fits as Ryan’s design intended but it’s almost 3x the weight too. Do I use that? It’s quite a bit heaver. I’ve already printed all the braces for the 32mm OD EMT conduit too… Thanks

In the USA, the target EMT for use on a LowRider is 1 inch EMT, which has an external diameter of 29.5 mm. EMT is sold based on its inside diameter, but for our CNC use we’re concerned about the outside diameter. 30 mm and 32 mm are options provided for overseas where our American style 1 inch EMT is not available — as other markets do things differently. The size to get is 1” not 1.25”

I am using 32mm pipes with 3mm walls, they are also quite heavy and not a problem for the motors, so you could try with those heavy ones.

I printed these off for my build. Thanks for uploading the files.

off topic, but where did you get that Lowrider IV font on your strut? that looks wild

@Neilp, are you hunting down this post? Doug’s strut with KnightRider vibes is pretty sweet.

i was curious about maybe lasering it onto my struts. Looks awesome. i found the logo dxf, and understand doug had to do huge edits to the ‘Comfortaa’ font to make that one.

@Neilp Feel free to use any of what I shared! I’d be thrilled to my design work utilized!

@azab2c Thanks for the share of the post!

After @azab2c pointed me in the right direction, I stayed up until 3 adding your and Ryan’s logos and nameplates to both my front strut AND a big engraving on my spoilboard (in lightburn). Can’t wait to get time in the CO2 to get these done.

Thanks for sharing your awesome work, as always, Doug.

Incase you/someone’s interested… shared custom strut with measurement markers and mini a LR4 diagram with holes for optic fiber light guides for the JackPot V1 endstop lights… https://github.com/aaronse/v1engineering-mods/tree/main/lowrider4/mods/aza-strut

Remember that there is a belt! It will cover a lot of your design, making it unreadable in pictures and videos. Ask me how I know. :sweat_smile:

The most important advice I can give, is to digitally draw the X belt across that artwork. If you cover up key elements with the belt you will regret it. Ask several how they know.. :slight_smile:

@Tokoloshe beat me to it… :slight_smile:

@Tokoloshe and @DougJoseph I hadn’t even considered that. Lol . Back to the drawing board

Thanks to you both

:100:, consider which Strut areas are obscured by the (slightly set forward…) X belt given the viewing angle(s) you care about. I designed with face on in-mind, but actually spend 99% of my time standing, and looking downward. I got dumb lucky for how dust shoe mod’s view port turned out. But, belt partially obscures the numbers when viewing from standing height…

Lasered mine as well.

…and an outline of the core. Gotta have somewhere to park it for those pictures!

Yeah, I blocked out the middle 8” for the core, it then added the honeycomb because I didn’t like the blank space. I’ll see that when the machine is working.

I completely blanked on the belt, so everything else needs redesigned, lol
