I bought 3 or 4 hotend cooling fans for some of my hotends. I just assumed that mounting screws would be included. I mean, you get two new hotend mounting screws with each hotend. While that is nice, only having an extra set included with the Bambu.
However, with the hotend fans, most people would buy extras to install on their hotends so they are ready to install. The mounting screws appear to be 2.5mm partially threaded screws. These are uncommon. Am I correct on the screw size?
Now until I order some 2.5mm screws, I have to transfer a single fan between hotends. Now, I need to put in an order to McMaster-Carr or BoltDepot with other screws and stuff I don’t need to justify the shipping.
I thought they were the same dimensions as the hotend screws you mention, but I assume you have confirmed they aren’t? Bugger, that means I too will need to source a bunch of them.
Out of all the fans purchased, only the most recent one included new fan screws.
For the rest I was forced to put in an order to McMaster-Carr for the 2.5mm screws. At least I get them in a day.
Luckily I found out all my fans came with the needed screws. Just for reference, they are M2.5x15 (2 mm hex head) while the hotend mount screws appears to be M3.5x14 (also 2 mm hex head though)
