[Suggestions on UM2+ 1.75mm conversion]

How much filament?  How much money?  If it's over $1000 then go for the conversion until you use it up.  If only say 10 spools don't bother.

 

3dsolex also sells a nice conversion kit.  For the UM2+ you don't need to modify the feeder at all.  That plus feeder is great.

 

You don't need to modify the bowden either as long as you are printing super flexible stuff (like TPU or ninjaflex).

 

You really just need a smaller teflon part.  The 3dsolex kit gives you an olsson block with a smaller channel and that teflon part.

 

In cura you can either try to convince in machine settings that your printer takes 1.75 filament (I did this once - not super simple) or you can just set flow rate to (2.85/1.75)^2 (265%).

 

If it weren't a business I'd just sell the stuff at half price.

 

I sell 3dsolex parts so I'm biased but the kit works quite well.  But... don't do it unless it's a LOT of filament.

Hi, thanks for your response.
It's just 5 spools, not that much. We've already ordered new ones at 2.85mm, but I figured asking doesn't cost anything and maybe there's an easy solution I've not yet realized.
 

[Suggestions on UM2+ 1.75mm conversion]

Hi everyone,

we've been using the Ultimaker 2+ on our campus for quite a while and we're generally very happy with its performance.
Recently, my boss ordered a bunch of new filament, but since he didn't know better (or forgot to double check) we accidentally ended up with a bunch of 1.75mm filaments.
Now, the purchase was made at the end of last year, so I highly doubt we have the option to return the unopened stuff as its mid March now.

That being said, I've been trying to solve this issue the past few weeks (or months ... I've kinda lost my sense of time during quarantine) by carefully calibrating the printer and printing a few new feeder parts to make the 1.75mm filament work. 

Spoilers: It didn't work. 

Since printing new parts doesn't seem like a feasible option, my remaining options are to either buy a third party conversion kit for UM2+ or to just give it up with the 1.75mm business and try to resell the remaining filaments.

I've tried to do as much research as possible on my own, but at the end of the day, I'm left with these two products that seemed like hopefully well-performing conversion kits:
https://www.gearbest.com/3d-printer-parts/pp_009724358436.html
https://www.dynamism.com/mosaic/mosaic-palette-ultimakerconversionkit.html

Does anyone have experience with either of these or some other succesful method for converting an Ultimaker 2+ to 1.75mm?
I'm struggling to find any kind of review online for these products and I'd rather not make my boss buy another useless thing that's just sitting around.
