Pollin Roulette case enclosure with 9V battery holder

thingiverse

I created a sleek enclosure for the roulette PCB electronics kit from Pollin (No. 810 163 - www.pollin.de). You will need to add an extra 9V battery and a 9V clip to get the kit up and running in that enclosure. The 9V battery fits snugly into a small rail underneath the PCB. Small posts at each corner keep the correct distance from the PCB. A little cutout lets the wire slide over the edge to the underlying 9V battery. Print the PCB at a low feed rate so it doesn't sit too tightly in there. The kit can be printed completely without supports and only requires a bit of rework, or maybe none at all, after printing. Printer: K8400 Rafts: No Supports: No Resolution: 0.1 to 0.25mm Infill: 15% Notes: A 0.35/0.4mm nozzle is recommended. Use a low feed rate so the walls and measurements are met correctly (e.g. 75% or less will do). Print speed can be very high because there's almost no need for retraction and jumps after slicing. On my K8400 with PLA: 225°C with 0.23mm resolution, 0.35mm nozzle and 65mm/s print speed (all types - infill, outer/inner, ...)
