Vinyl Record Hanger designed to hang small to large records using flat thumbtacks (0.42 - 0.43 in base). Support holes are 0.435 in (11.049mm)

5 Degree slope at mounting point for a little extra hold in the sheet rock

Printed at .2mm with only a skirt. check for supports if your machine does not do well with the upper slope.

I used these upholstery tacks in wall because of the longer shaft length. but you can use nails or any other pushpins that have a flat top
