EinW 3d printed VESA 75 wall-mount

Needed a short bracket for a VESA 75 monitor Leave a comment

Searching the same old on-line shops and market locations yielded nothing dainty – if they’re made for VESA 75 (74 x 75mm gap spacing) they’re additionally made for VESA 100 (100mm…) and beefed as much as carry 32 inch full-weight screens and attain out a number of hundred millimetres – so far as I might inform.

As regular, it took a whereas to hyperlink the un-met want with the existence of a 3d printer within the constructing, however finally the penny dropped and the factor within the proper is the consequence.

Admittedly, there have been a couple of prototype bits and items printed in between, and a go to to Screwfix was essential to get appropriate 15mm washers, however complete design time was most likely round two hours.


As an thought of dimension, the 2 arms are 75mm lengthy and 15mm thick, printed in PETg with a 2mm shell and 30% infill of a Prusa Mini.

It simply holds the 1kg. I feel the wall-mount half (proper aspect) might have been taller and narrower, and the washers contained in the joints usually are not wanted – permitting the arms to be a little taller (given the bolts that had been obtainable).

The outer load-spreading washers appear wise.

PETg was used as a result of it doesn’t creep as a lot as PLA underneath fixed load, and fails in a flexible manner* if over-loaded, quite than abruptly snapping.

BTW, the monitor is so skinny that 2mm appeared the utmost size of screw that would enter the M4 threaded holes behind the case – barely two turns of engagement because the thread of a screw will not be totally shaped at its tip. But it appears to work.

 

*I’m certain mechanical folks have a correct phrase or phrase for this, however you get the concept.
