This is my attempt to duplicate a walnut record holder I saw on Etsy. (https://www.etsy.com/listing/1789740187/solid-hardwood-record-flip-rack-record)

Should hold about 25 LPs and allows you to easily flip through them.  I'll post photos after I print.

If sharing, please provide attribution to @WiltwyckMidCentury on Etsy as they are the original designer.
