EMT (Electrical Metallic Tubing) Conduit 3/4" Fittings by stugpanzer

Last crawled date: 3 years, 1 month ago

I have some 3/4" EMT Conduit tubing laying around my house which I will be using for making a snow cab for my riding mower. The EMT Conduit is very strong and much can be done with it outside its original purpose of running electrical wire in it!
I have searched around for some fittings and was not having much luck so I designed some fittings that I have not yet printed but intend to as we approach the end of summer and into fall.
The parts I designed are what I believe I will need to use to build the tractor snow cab but as I start designing that project and if I realize I need something else for the EMT conduit then I will add it to this thing listing.
Each fitting has a 1/4" hole that is intended to be used to bolt the EMT in the fitting by drilling a hole in the EMT and passing a bolt through the fitting and conduit.
For those that may not understand the intended purpose...these fittings are not for use as electrical conduit fittings to run electricity with! they are more for making structural items out of the conduit combined with these fittings.
I have included the STL files as well as the original 123d Design files so you may modify as you desire.
I intend on printing these in PLA with anywhere from 60~100% infill. Should be able to print without supports or raft. I will probably print the prototypes at low res and 30% and go from there and will revise this as needed.
UPDATE: Added two more parts.
UPDATE: I started printing and at 30% I feel these might be very strong for the purpose I intend on using them. I will continue adding photos and updates as I proceed further.
Update - 08/25/2017: I fit some conduit in the parts I printed. They are really tight so I suggest you increase the part size a bit when you slice. I will be testing with another single part and will advise what to increase to (percentage). I believe I will test by increasing by 3% when I do. I added some photos of the parts with the conduit pushed on.
Update - 09/15/2017: I printed some 45's and increased their size by 5% and they fit easily onto the 3/4 conduit. It might be too loose for some but it will work for my application. Next time I will print at 3% increase and see what that gets me.
Update - 09/17/2017: I printed some TEE's and increased the size by 4% and still an easy fit on the 3/4 conduit so now my next print will be 3% increase as I think that will be the magic number.
