I was replacing a lamp bulb in an Ikea 'Lock' lamp. In the process of putting the glass diffuser back on, one of the original plastic clips broke off. Apparently the plastic of the original clips becomes brittle after some time.

So I printed this replacement parts.

Protip: when printing this clip, print multiple of them in one go as while I was putting the diffuser back on with the replacement clip a second original lamp clip broke off :-)
