The Olsson Ruby is a high-quality nozzle by 3DVERKSTAN. It's designed to print highly abrasive materials while retaining the excellent heat conductivity of brass.

The Olsson Ruby will work with a huge range of materials. PLA, ABS, CPE/PET, Nylon, and composites with abrasive additives such as Carbon fibre, Steel, Wood, etc.

The ruby mounted at the tip makes sure that even the toughest materials will be printable. It was originally designed for printing with Boron Carbide (B4C), the third hardest known material in the world.

Since most of the Olsson Ruby is made from brass, with its excellent heat conductivity, performance and throughput is first-class.

Happy so far.The Ruby nozzle initially bottomed out (no gap) in my trial fit from the OEM brass one. So, followed the instructions, cleaned and reapplied thermal paste, reset gap and put it all back together. Reset z-height from 0 to be safe but it ended up back where I had it before replacing the nozzle as I was careful to use the same shim for step 25 MINDA/PINDA initial height. RTFM;https://help.prusa3d.com/guide/how-to-replace-a-heaterblock-heatbreak-mini-mini_122769Prusa documentation is excellent.

Don't believe the hype.Even if you manage to install the nozzle which can easily break if you over-torque it, it is still very prone to all sorts of print errors.The nozzle's strange outside geometry makes it prone to get filament blobs compared to the normal chamfered nozzles.The internal diameter is wider than the filament path and they have just put a cylinder inside to match the filament diameter which is not even attached to anything (you can pick it out). The gap between the threads and the cylinder makes the heat transfer uneven.The ruby itself is not safely attached to the brass and can detach if not careful. Of course it can chip if it hits the bed.It worked for me for maybe a year or so. Now something has happened so filament starts leaking not from the orifice but from the seat of the ruby.For the price of one Olsson Ruby, you can buy three Nozzle X or similar durable nozzle and you will have zero problems.The Olsson Ruby is shamefully priced considering the cheap build quality of it.

I have now been using the nozzle successfully for several months on my MK3S+.During this time I have also used a lot of abrasive materials and am still very satisfied.A higher setting of the pressure temperature, as it is recommended in some forums, was not necessary for me so far. Probably because I print in a housing and thus an additional cooling of the tip by external influences does not play a role.It is absolutely necessary to follow the somewhat specialhandling instructions, because the tip reacts very sensitively when it comes into contact with the printing plate or with a wire brush (during cleaning).So read first, then use!
