Seek and yea shall receive Mr Kermit Sir!!

To start off, this is what happens when the print come unstuck from the build plate (and you forget to check it regularly). This was going to be the tail section.

It’s only happened once so far & I have taken onboard some great advice from Gerald to force feed the filament for a few seconds when starting a print with LW PLA. As it’s a foaming filament it tends to ooze from the print head before it starts the print & then doesn’t stick well. A quick force feed seems to fix the problem. I suppose another option is to edit the print GCode but force feeding is easier.

 

This is where I started the mini Cub project while waiting for the LW PLA order to arrive. This is the complete landing gear printed in PETG (for strength) with TPU Flex printed tyres & stainless capscrews for axles.

The whole assembly weighs in at 44.2 grams which is correct weight according to the instructions (once you deduct 2 grams for the SS wheel bolts & nuts).

The rubber band is the shock absorber that allows the assembly to flex on a hard landing.

 

  

This was my first LW PLA print. It is the centre section of the main wing with the second pic showing all the internal bracing. It weighs in at 9 grams which is 3 gm lighter than the original.

 

This is the fuselage tail section showing the recessed joining lip & the internal tubes for the elevator & rudder control wires.

This piece weighs in at 8 grams which is about 2 gm lighter than the original.

 

This is the start of the fuselage front section (complete fuselage prints in 4 parts) and this part alone is a 4 hour print (I think the longest of any part on the mini Cub) and will weigh in around 26 grams when complete.

 

Nose section print has finished @ just over 4 hours & weighs in at 20 grams so it looks like the eSun LW PLA prints lighter that the filament supplied by 3Dlabprint.

Front part is the PETG Motor mount.

More to follow eventually.
