Underware/Multiboard Permaplug rewirable 4 x UK power socket holder (Onshape)

Underware / Multiboard attachment for Permaplug rewirable 4 gang socket. 

This is sold by 

• Screwfix as “Masterplug” under stock code 90230
• Toolstation as “Axoms” under stock code 59015

It attaches without getting in the way of the sockets

The base is attached direct to multiboard via a pair of snap connection. Then use the band to connect the plug without interfering with the sockets. There is a choice of two widths, one standard (about 25mm), one extra wide (45mm). The Extra Wide is helpful if you've got a tight space and need to be able to move the power strip a little more left or right. 

The band has clips, these need to be pushed hard to insert, but will retain well once installed. It's generally easiest to attach it to a lose bit of multiboard before you try to do the same under your desk. 

The socket doesn't fit particularly well with the standard underware holders (The last plug is really close to the edge), and I didn't really fancy the adhesive options (I never have a lot of luck with glue). The design doesn't need a lot of filament. 

I chose a rewireable design because if you're going to all the trouble of underware, why wouldn't you want cut to size power cables?…

Printing

• PLA Worked well for me
• You probably don't need supports, at least with PLA
• I used a Standard Multiboard configuration - 3 Wall Loops, Gyroid, although Prototypes with 2 loops and grid seemed OK..

Onshape aspects

I imported the STL for the Snap connector, and then built the holder around it in. I didn't make it parametric, but it's certainly not going to be rocket science to adjust if you wish to build something similar or move the parts a little to better fit your design
