Summary

This mount is design the have the IKEA Markhus (https://www.ikea.com/nl/nl/p/markhus-zachtsluitend-beslag-voor-lade-60426571/) screwed at a 90 degree angle.
Which is useful for example when you want to install the softclose module on the IKEA Hemnes bed (https://www.ikea.com/nl/nl/p/hemnes-bedbank-met-3-lades-2-matrassen-wit-agotnes-stevig-s79428117/) which has no side walls to mount the Markhus to.

For 1 IKEA Markhus softclose unit you need to print 1x "Mount Back" and 1x "Mount Front", since the holes that are used to hold this mount are slightly offset.

Print with the side facing down (so the pin is facing up)
