FYSETC 3D Printer Parts Flsn Q5 - MP Select Mini V2 Silicone Sock: BP6 Heater Block Silicone Cover Hotend Protect for Anycub i3 MegaS Chirron V5 Hotend - MP Mini Delt - Flsn QQ-S pro-Pack of 3

Fit my MPMD v2’s hotend perfectly. Just a quick snip to make a slot so I didn’t have to remove the thermistor and heater cartridge and it slid right on with a snug fit. Make sure to do a PID autotune of the hotend after installation.

The original insulation on my MP Select Mini V2 got stuck in a print one day and ripped off. I went without anything for a while, but got occasional errors about heating (I think the room was too cold for the hotend to get up to temperature without insulation). I haven't had any errors with the ~10 or so prints I've used this for so far.I was afraid these socks might get caught on prints, because they aren't tight - not loose exactly, but not tight - but they seem to be fine.One catch, about installation - one of the holes in this sock goes over the heater cartridge, so ideally you remove the heater cartridge, install the sock, and put it back. I didn't want to go through the trouble, so I cut a slit in the sock and slipped it on; again, it seems fine with that.

The sock is a nice quality silicone. It fits excellent! The only issues I have are what you see in the first two pictures. One shows the hole for the nozzle is not cut in the correct location. The nozzle bit off from the cut out hole. This is with all three that came in the pack. I don't think it will cause any problems with filament. Also one side of the heat block has some random cut out. I don't know if this will affect the heat retention for the block.I don't know if I should keep these or return them. I have silicone socks on my other 3D printers that do not have the same issues I have pointed out. I would prefer to not have the odd extra cut out and better positioning of the hole for the nozzle.

I purchased this silicone sock to replace the cotton insulation and Kapton tape on my Delta Mini factory hotend. It had a good fit around the heater block without using any cotton or tape. However, the alignment of the cutouts for the heater cartridge was not the best and required stretching of the sock around the cartridge to put the cartridge back into the heater block. There was no opening for the set screw that is near the nozzle to tighten the cartridge, and once again I had to stretch the sock nozzle cutout to get my allen key into the set screw to tighten the cartridge. I would recommend the manufacturer consider adding a small circular cutout for the set screw adjustment. Otherwise I would have given this sock a 5-star rating.

No issues at all. The silicon smells a little bit on first heat up, but that is expected. The nozzle, thermister, and temp sensor holes were all correct. It does have 2 holes on the one side, but think it is to allow it to work on a few different model hot ends. Fits as expected on FLSun Q5 printer. Nothing bad to say about it.

i got these to use on my kingroon kp3 printer. an have since realized the also fit my flsun qq-s pro so i have got them on 2 of those an plan to pick up more later on. they are the correct size for the heat blocks but they dont have all the cut outs for the heater cartridges an thermistors so u will have to cut or trim to get them to fit but its just a small amount so its not even noticeable. they are smaller than what comes on a ender 3 which is what ive seen to be the more common but for anything that is 16mm x 16mm blocks this will work with some trimming.

Giving this less stars because you aren't using it on a Monoprice Select Mini V2 isn't helpful, just saying.These fit nicely without cotton and tape - it would be stretching things to try and use them without first removing the old tape and cotton. Would have given this 5 stars but at a couple of points on the sock the silicone is very thin and you need to be uber careful when pulling the wires through the openings. Take your time and be careful and you get one or two more chances (it's a multi-pack) if you try to move too quickly.,FWIW, my SainSmart Ender 3 came with a silicone sock and no cotton or tape, so with the great fit on my Mini V2 that these provided, I am happy with the solution.

This item says it works with the monoprice mini Delta. And it does. It just requires minor modifications. With all other tape being out of stock for months this is a fantastic alternative. It is study and reliable, and comes with 3 socks. This might be the last insulation you buy. Would definitely recommend!
