20mm rear cover for Touch 2 case for piCoreplayer with JustBoom Digi Hat

thingiverse

##Description## These parts are for a piCorePlayer along the lines of the one described here: https://alw-audio.co.uk/?p=728. Instead of the Touch case described in the article, I used a Touch 2 (https://smarticase.com/products/smartipi-touch-2), which provides a hole suitable for the IR receiver, to save having to add one myself. The vendor offers two backs (https://smarticase.com/collections/all-products/products/smartipi-touch-2-back-cover) - either a 15mm (1 or 2mm too small) or a 35mm one (too big). Fortunately, the vendor makes the CAD files available so I modified the 15mm back to make it 20mm deep and added access holes for the audio ports. If not using the coax port, there's a plug for it. There's also a bezel for a red filter (cut from a sheet of red gel) to cover the IR receiver. ##Slicing and printing## Flip the cover onto its back to slice and print. The case was sliced with Cura 4.8 (0.2mm layers, 100% infill, adaptive layers, tree supports) and printed on an Anycubic Mega S. Time to print the case was just short of 11 hours. Supports came off pretty easily but some sanding may be necessary to clean up. The bezel and plug were printed with 0.1mm layers, 100% infill and adaptive layers, no support and each took less than 5 minutes to print. ##Acknowledgements## Many thanks to SmartiPi (makers of the case) for making the original file available and giving me permission to publish here.
