IKEA Markus chair arm

These are smaller arms for the Markus chair to enable it to fit easily under a desk, the final height is 160mm from the bolt centreline. The design is loosely based on Hichi's but reduced to fit on a standard printer with a 250 mm x 200 mm bed. I have embedded the bolts fully in the rim to get better stiffness. The design is symmetrical and attaches using the standard bolts.

Update 18/08/22 at the request of Paveluska I have designed and open fronted version. I can't comment on the strength of this as i haven't actually printed it. I also added a squarer design to match the Ender 3 print envelope so this is taller but not as deep front to back. Finally there is open ended large which is about the same size as the original Markus arm but with an open front end, this needs a bed of 300mm x 300mm.
