Ultimaker Hot End Accessory Mount

thingiverse

A 2 part mount that wraps around the top of the Ultimaker hot end, with recessed slots that let you easily mount things; in particular, the slots are positioned to properly mount 40mm and 50mm fans vertically flush with the edges of the hot end. Will not interfere with existing stock or most custom fan mounts. Instructions Print the two parts; you will need to use support because it has flush overhangs. Remove the support and file things nice and smooth so the parts will fit together well. There are two side holes in each part; tap the inner (smaller) ones with a #6 tap or similar metric size. To install, remove any existing fan mount, then remove the two long bolts on the left side of the hot end, put two extra nuts on them and spin them most of the way up the bolts, then add either of the parts and reassemble. Gently tighten the new nuts to lock the part in place. Repeat the process on the right side, then use two small #6 bolts in the side holes to lock the two parts together. Reinstall your fan, and now you have 4 adjustable mount points. You will find that most 40mm fans can be tapped #6, so you don't need long bolts to mount them. Buttonheads are preferred because they are low-profile; so long as they don't project above the slots, you will not have any interference problems with the sliding blocks.
