The clip which comes with the Up! mini to hold the filament doesn't really work very well. I had the filament pop out a few times so ended up gaffing in it in place.

It looked a bit ugly so I decided to print a new part to replace it which worked properly.


  1. Rotate to your favourite printing orientation.
  2. Print
  3. Unscrew old clip & replace
  4. Clip in filament and slot in tube.
  5. Print and Enjoy.

This was my first print on the mini ever.. came out PERFECT, the mini is an eye opener if you're used to a DIY printer like me.., thanks!

Thanks! I printed it and this works perfect. It's a lot better than the original one.

thank you !! this works great!!

Very nice, I also heard of a tweak with adding some tissue paper between
The clip and the filament. This cleans the fillament from dust wich improves the print quallity.

How are your experiences with the up? Im looking into buying one.

Could potentially be added to this. I am sure at some point there will be a derivative. 

Just to put this in perspective I have been in possession of a RepRap style printer for the last 2 yrs. As I got a TechZone kit, which was a huge mistake, one of those years was spent learning how bad that kit was. I then bailed and bought all the parts for a prusa mendel, which relative to the kit, was an absolute dream to work with. 

I used it up until about 4 months ago, I had to print a series of kit shells for a robot workshop I was running. It did a valiant job in churning out a heap of parts. It ran 24hrs a day for pretty much 4 weeks, with my various revisions and then 15 lots of the finalised parts.

Unfortunately by the end of this, it was pretty broken. I had printed all the bits out of ABS for better mechanical properties and this higher tempt took its toll on my printed parts. At the end I had to call on a friend to print the last few parts for the robots. My heated bed was screwed, my hot end crapped out and I had all sorts of issues with my belts and motors. 

At this point I spent a few months trying to revive it. New belts, new pulleys, new bed... ect. But it was never the same. So I bought an UP!. Mini. 

First thing I should mention. The UP Mini still has QA issues. (If I could put this in bold.) 

However, my issues consisted of the bed not being level and my extruder having some filament stuck in it. The levelling was fixed (mostly) by adding a washer. And the extruder was removed with two bolts and the excess filament removed. 

Don't get me wrong I was more than a little pissed when I got it out of the box, fired it up and it didn't work. But I have to give credit to Bruce at 3Dprintingsystems for his support and assistance. 

And let me say printing with the UP is very different to printing with a reprap. Once I had resolved my initial issues that was pretty much it. You make model print and then the part exists. Oh and let me just say the support structure to hold up overhangs and what no is simply amazing. NFI how it does it so well. 
Some dude is ranting about how the mini clips are a failure point. http://www.thingiverse.com/thing:34594http://www.thingiverse.com/thi... and while he is in spain and appears to have run into issues with his local supplier I don't think this is worth putting you off buying an Up Mini!.  These clips may break in shipping but I see no reason why they would ever break once your machine is running. Angus (vvvv below ) received his mini with a broken clip but got it replaced. And its now working fine after he was sent a replacement by his reseller. 

So in summary I view the UP! Mini as a tool. Its filament costs a bit more and it costs more up front. But (for the most part) it just works. I draw parts and I get them. My RepRap I spent 80% of my time trying to get the best parts I could. Rather than actually worrying about what I wanted to print. I am not saying it wasn't fun. Or a great learning experience. Just not what I wanted anymore. I need parts for stuff I want to make. Sort of over trying to work on my own printer. 

Anyway long rant but hope its helpful.Steve

Just a way to make public the issue of the faulty mini printer: Cube support for 3,25mm. rods

Thanks for the input. I read about the bed levelling issues. It puts me off a bit, but I did see that they have a software fix for it now and that you also can use washers as you said. So it looks like this isue is solvable. In the end i'm looking for a printer that just works when I need it to. I don't mind maintenance but I'm not looking for hours of finetuning and testing before I can print.

Did you also tried printing in PLA? (I don't really like to print in ABS because I get a headache of the fumes). I could not find any options in the software to alter the tempature of the extruder, so I wondered if you can lower to the optimal tempature for PLA?

Yeh the software fix isn't 100% I found that I had better results the more flat & level I had the bed but its an easy fix. 

I have not tried PLA but there is a PLA setting. I have found that you are pretty well locked in to using the PP3DP filament due to its specific melting point and width tolerances. So most people just use ABS. I haven't really noticed much of an odour or fumes from the printer but I wouldn't want to be working next to it in a confined area. 


Works soooo much better, a must for any up mini owner. Original simply does not work and leads to the spool jamming.

Thank you for this, until now i have been getting by using wire to hold it in.

Hope its working. :)
