Here I got a tricky one to print.
It's a frame replacement for the remote control of a Philips SPA7380 sound system. Now you can change that red ring according to your home desk colour scheme.
Since only the areas around the 3 holes have contact to the printing bed you need some good support settings for this one. I used slic3r for the sclicing.
Printing resolution: 0,1mm
Support contact distance: 0,075mm
Really slow bridging speed: 20mm/s
The volume knob is simply plugged onto the rotary encoder. Use a flat srew driver on one side to lever the knob from the remote control. Stabilize the knob with your fingers so that you don't damage the encoder. Mount the new frame and be happy.
