Barcode Scanner Cradle and clamp

thingiverse

This barcode scanner assembly is built to mount the Jadak H1S series barcode scanner on a Philips TC70 ECG machine. Built with PET-G 2.85 filament on an Ultimaker 2. The filament was the white gear from radionics.ie http://ie.rs-online.com/web/p/3d-printing-materials/8919337/ The articulated arm was recycled after decommissioning an old ventilator. Any sort can be adapted by modifying the files to suit what you can find. I ran a M8 tap as far as i could in each end of the arm, this allowed 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 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/
