Late to the party here but I am doing this exact thing. I stupidly bought like a dozen rolls of 3mm filament for about $6 a KGKg. I think trying the switch should be fun...but I have 7 printers so its no big deal to tinker on one of them.

What you need to do is modify the extruder. I have done this successfully using the crappy plastic extruders which come with most budget printers. You have to drill out the filament path to fit the 3mm3 mm filament. It does get a little tricky to get the filament to run through nicely.

You actually DO NOTdo not need to modify your hot end other than your bowdenBowden tube and your nozzle. Regular bowdenBowden tube is 2mm2 mm ID and 4mm4 mm OD, so you just order 3mm3 mm ID and 4mm4 mm OD tube. Please note that this plan WILL NOTwill not work for an all metal 1.75mm75 mm hotend.

For the nozzle you can often find 3mm3 mm compatible nozzles. Unfortunately they don't seem to be made for the MK10 hotend. So I simply ordered big ole 1mm1 mm nozzles made for 1.75mm75 mm and I am going to drill out the back for the 2.85mm85 mm (3mm3 mm) filament.

I am excited to see how this all works. You can get some really good deals on 3mm3 mm filament ANDand I suspect that it will actually work much better for things like TPU since it is significantly more rigid due to the increased diameter!

You actually DO NOT need to modify your hot end other than your bowden tube and your nozzle. Regular bowden tube is 2mm ID and 4mm OD, so you just order 3mm ID and 4mm OD tube. Please note that this plan WILL NOT work for an all metal 1.75mm hotend.

For the nozzle you can often find 3mm compatible nozzles. Unfortunately they don't seem to be made for the MK10 hotend. So I simply ordered big ole 1mm nozzles made for 1.75mm and I am going to drill out the back for the 2.85mm(3mm) filament.
