We’ve been trying to reassemble the Ultimaker after fixing it, but couldn’t find the allen key to tighten everything back. We’ve got the set of new ones from a regular store, but there wasn’t anything that fit the screes.

All of them are either too big or too small. It seems that Ultimaker has very specific ones. And they don’t sell them either. Anyone has been in the situation?

Cheers

Are you using METRIC allen wrenches? Because I bought my UM1 used and it came with no tools so I’ve just always used standard metric sizes.

If you’re in the US, you probably didn’t get the right size allen keys. Ultimaker is from the UK, so their allen keys are going to be metric. In the tutorial, they mention the right size metric allen keys for you to use before each section. Just gather up all the sizes from each section and bring them to a hardware store and tell them you need metric allen keys. They should be able to help you with that.

Can’t you change the screws ? Try to find a similar screw but with a different head.

Maybe you should try to tie a magnet to a rope and throw it under your furniture to find it back.

otherwise, I’m sure that ultimaker support will help you either with the right size you need or by sending you new ones

Most of the screws should be 2 mm allen key. Ultimaker 1 or 2?

I had this problem in our case we put it down to nackered screws. They must use cheap ones

I am going on a leap here and guess you bought Imperial keys, If so, try Metric keys (2mm). They should fit. Dutch manufacturer.

They are standard metric readily available even in USA ( Mcmaster Carr problems). Ultimaker is from Holland not UK.

Yep-- they’re metric, not SAE. Most of them are 1.5mm & 2mm, with the really tiny ones at 1mm. If your local big-box hardware store doesn’t have a set with the smaller sizes, check a local RC hobby shop or (much cheaper): http://smile.amazon.com/dp/B00I5TH074 3

Ultimaker along with most 3d printer manufacturers use metric with printers so you’ve likely bought imperial sizes.

I think it is very likely that you purchased SAE Allen wrenches rather than metric Allen wrenches. If you get the metric ones you should have no more problems. Please let me know if you have anymore questions

Wow guys, thanks for such great response! we actually bought them in Amsterdam so its pretty silly that they don’t have something fitting. The one I have here seems to fit well, but its like a tiny bit too loose… I am afraid that the part itself might be worn out or something :confused:
