No worries at all. Let me see how I could figure out where there are a few tweaks to make and I'll post them here. Nether the less, great design! Looks stealthy
I'm not sure what I've done wrong. But when I want to mount it to my Ultimaker2Extended the Fan Mount touches the front right screw of the hotend carage. When looking underneath the Hotend does not stick out enough. Is this an Extended "problem"?
I love this holder. Would it be possible to get the Core 2 in a 100mm version. Some of my 1KG spools are a lot deeper and therefore don't fit on the 80mm core.
I added a few "wrinkles" to the knob so that it does not slip when grabbing. Thank you for uploading the SLDPRT for easy modification. Not sure how to upload a remix of it yet.
Further I wanted to note, that you do not need to glue something on the knob to get it out. Just take the hex key and push it out from the back (there is a little hole).
