Do you have a pair of Bang & Olufsen Beolab 6000 speakers? Do you have a 3D printer? Do you want to avoid paying £400 for a set of wall mounts for your pair of Beolab 6000s? Well look no further!
That pretty much explains this post… I designed some 3D printable wall mounts for the Beolab 6000 speakers. You can even download them and print them yourself! They’re not perfect, but went through a fair bit of development and planning to make sure that they won’t fall off your wall. Plus it only costs a few pennies.
I ended up using a two part design to minimise layers under tension and increase strength. I didn’t manage to mitigate this completely, although it could definitely be refined with future versions. A dovetail piece is screwed into the wall, and the second piece interfaces with the Beolab mount.
I also did some crude destructive testing to figure out where the design would fail, and tried to eliminate the failure points where possible. I found that the moment forces were trying to rip apart the layers on the dovetail – so added some bowties to try and strengthen them. If nothing else this added more wall thickness and strengthened the design that way.
The initial design was meant to be printed in carbon fibre reinforced ABS. It’s very rigid (about the same UTS of PETG) so would stop bouncing and bending – given the original mounts cantilever design. It’s pretty expensive though, and with how many revisions this would take to get right, I quickly decided to redesign for PETG – which I had plenty of. This did mean thickening up the design to get the same stiffness though… which didn’t look as sleek. The carbon fibre had a really cool finish as well. Oh well. It means it’s easier to print for everyone else too.
As always, I made instagram stories about making this. Best way to understand what I was thinking at the time:
