Barcode Scanner Cradle and clamp

thingiverse

This barcode scanner assembly is designed to secure the Jadak H1S series barcode scanner onto a Philips TC70 ECG machine. Built with PET-G 2.85 filament on an Ultimaker 2. The filament used was the white gear from radionics.ie. http://ie.rs-online.com/web/p/3d-printing-materials/8919337/ The articulated arm was salvaged after decommissioning an old ventilator. Any type of arm can be adapted by modifying the files to suit what you find. I ran a M8 tap as far as possible in each end of the arm, allowing me to use an M8 countersunk bolt for the arm - cradle part and a M8 cap screw tightens the clamp assembly. The cap screw has a rib cut into it by a Dremel or hacksaw. The lower clamp is placed over the cap screw followed by a suitable cir-clip around the rib to retain the lower clamp when removed to reduce parts count. The upper clamp - arm is a friction push fit and is retained then my the cap screw. The settings used were: Nozzle 0.4mm Layer height 0.06 (to reduce artifacts as much as possible) Shell and top and bottom around 2mm. Infill 70% Speed down at 25 mm/s. Temp 244 degrees celcius Bed around 90 Fan at 69% When printing with the PET-G my printer worked best if it was calibrated with a bit of card instead of paper. After a while I got used to adjusting it live, i prefer it as the printer can be a bit wonky. The nozzle seems to lay the plastic rather than spread it with the nozzle like PLA. There are plenty of guides online to learn a bit more about the material. The end finish should be fairly smooth. It was passed by infection control before use. Here's a guide that is quite useful https://letsprint3d.net/2017/08/08/how-to-print-petg/
