Repbox 1.5 Fittings for PC4-M10 Pneumatic Couplings

thingiverse

The new fittings/connectors for the Repkord Repbox version 1.5 are very unreliable. Not only are the connector threads insecure but the fittings barely hold on to 4mm ptfe tubing without serious force. Additionally if you have the sealed version of the repbox the connectors are no where near airtight and can't be closed when not in use. I remixed motocoder's awesome drybox connector to fit the Repbox 1.5 and these are far more secure and airtight. I printed everything in PLA and have no issues with parts breaking. You can use these connectors on the passthrough to attach the tubing: https://www.amazon.com/gp/product/B01IB81IHG/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 To install simply push the passthrough into an opening and use a Nut to secure it. I used a little tack on the passthrough to seal the hole rather than using a gasket. The nut is very close to the dimension of the hexagon cutout on the inside of the box. You can then use the Second Nut to further secure it or the Cap if that opening will not be used.
