Broken Delrin Clip UM Original

[philip 1]

Hi all,

I broke the extruder Delrin Clip of my UM original.

I had a look on the web and a guy has replaced with an e-clip. I bought myseld few of them and I applied two.

I am asking if they are going to be good or they can cause malfunctions or breaking the 3D printer. What do you think or did you have had the same experience?

There should be the stl available on Youmagine, but it seems the website is down, I can't access it.

The Delrin Clip received with the 3D printer has a different and I am wondering if this shape is necessary for keeping the wooden gear in place.

I have to leave the machine working this night and I do not want to break.

Many thanks for any kind of answer!

Basically you just want something with little friction, to hold the hubbed bolt in place... Using a few e-clips should be just fine...

If think its a good idea to put ad many as can fit, to make sure there is no play in the position of the bolt and gear...

Thanks for your super fast answer! I am doing a print test, hopefully is gonna work!

The STEP file for the clip is available here. Should work just fine to print out a copy:

Your fix will work as well, but it's convenient to be able to quickly remove the bolt for cleaning.

An update: two replacement e-clips were causing under extrusion.

The thickness of these two together was more than the original Delrin Clip. I removed one and now there is no under extrusion. However is it normal that the wooden gear is not perfectly aligned with the motor gear? I also notice that after a while it went back aligned.

Anyway, I will print a copy...thanks IRobertl for sharing!(I just have to figure out how to convert a STEP file in an STL... :???: )

Alright... pretty impressive that the e-clips can cause enough resistance in that position, to cause under extrusion...:/

In terms of the gear, I'm pretty sure the build instructions say they should be aligned... Here are the instructions:

However, I am also confident you can print the (very small) clip with them slightly mis-aligned...

This can maybe convert the file for you:
