OK. By real world standards, this does not really qualify as a disaster. At best, this is more of a drama queen statement on my part because I apparently have wasted ~2kg PLA and a week of print time.
I would question whether there are erroneous MPCNC Primo “J” 2.54 files on the Printables website?
First, I am assuming these are the correct choice for 1" ID EMT.
I printed and tried fitting the core clamps to the EMT first and they are good. I then proceeded to print all the rest of the parts, but none of the sized parts fit. Where/when stamped, they are all marked “J”.
" There are 3 different sets of printed parts C-23.5mm, F-25mm, or J-25.4mm (1 inch). The measurement is for the Outside Diameter of the conduit/rails/tubing. Please measure your rails before printing! 23.5mm fits ¾″ EMT conduit in the US. Anywhere else you must physically measure first. Some things are sold as Inside Dimension (ID) (conduit), or Outside Dimension (OD) (tubing)."
Best not to assume, best to check the documentation!
Unfortunately, there are no options for 1" ID EMT. If you want to use conduit you’ll need to get 3/4" EMT and print the 23.5mm ‘C’ version. If you want to keep your 25.4mm ‘J’ version then you’ll need to look for some 25.4mm OD pipe/tube.
