DIY a Knockbox under RM10

This is a DIY project from our friend Irving.


This is what I call a savvy. I always have this admiration for people who can DIY. I’m really one of those DIY idiot who can seems to make anything with my hands.. except coffee 🙂

I remember when I was in secondary school, my best friend Oliver who is another DIY genius, gave me one of those air-craft model that came in many plastic pieces. I totally make a mess of it. My best result is an airplane similar to the one from LOST, if you know what I mean.

Ok, here’s the step to a functional and cheap knockbox.

From Irving:

Anyway, as promised, here are some pics of the knock box I’ve made for under RM10 I told you about. Here are the list of materials:
1) Swordman plastic container RM3.90
2) Handle of a cheap pine-wood spatula (Spatula costs about RM3 from pasar malam).
Problem is I’m not sure where to get them now
3) Rubber tube from a car door edge bumper – I replaced mine for RM6.90 (for 4),
and I used the old one for the knockbox. So you can say it’s RM1.75 for this

Hey Irving, make me one lah… pleaseeeee… I compensate with a pack of 250g Supremo blend ok ar?

    Question: Does it topple over when you hit the portafilter against the rubber part of the knockbox? I believe if you add some weight to the bottom of the plastic container you will have a perfect knock box. Just me 2cents….

    Hi Venky, that’s a very good question, in fact that was the first question KFChan asked. The knock bar was positioned closer to the centre to prevent this. It has not toppled so far.

    Chan, thanks for posting this. We can have a “try-before-I-build-you-one” session… Next barista jam later this month, perhaps?
