MicroSwiss 1/8" PTFE Fitting adapter

thingiverse

I'm finally done with the stock attachment of the PTFE tubing on the MicroSwiss direct drive kit. I lost the original locking disk and the metric replacements aren't going to cut it. they are either to loose and the tube ends up twisting when the printer moves. That caused some issues with flexible filaments like TPU. This part can tilt a little bit during printing but it can't twist. The tapered cut on the end of the tubing stays aligned to the extruder wheels. Time will show if this is a viable solution This part is held in place by the extruder assembly. You don't need any anything but the fitting. Mine is a 1/8" NPT but you can use something else and use the customizer Try the supplied measurements first. If it doesn't fit change the model parameters. Everything is documented. Avoid scaling it. It printed in 8 minutes and it took only 0.6m or 2g of PETG. I used 0.3mm layers and a 0.6mm nozzle
