I really like design of IKEA BJÄRNUM, so I created printed version which can withstand up to 4 kg (50% infill).
- M3 x 20 mm philips screw,
- M3 nut.
How to print
Both parts should be printed sideways and with supports.
_mount should, be placed on build plate with nut hole up.
_mount should be tightly screwed to true surface, and then mount rest of the body.
Design have locking mechanism, if it's too tight you can trim the bump on mainbody.
