I am having trouble clearing out the internal supports on the speedbrake and flap lever parts. I cannot seem to get the supports out without seriously braking the levers, printed as per the instructions.
How did you guys do it? Did you drill out the supports?
Hi George, yes I found it quite weak also, broke 2 trying to simply remove support material even 100% solid print. I designed a modified one as a caddy like Karl has done on the Flaps Lever side and used a piece of aluminium bar which was also used for Flaps lever to make an upper stem to the handle and it works well now and is very strong.
If you want the STL file to print one to try let me know and I will add it here
Hi Ross
Do you find that the speed brake is strong enough? Mine seems to break at one of the screw holes where it attaches to the speed brake knob. I'm using standard PLA but am considering using ABS.
Thanks, I am going to try that. I had the interior of the tube filled and no way to get the supports out.
G'day Dakleton, I printed mine lying on its side with the indicator arrow facing upward on the top layer
I Used Dynamic Quality 0.16 which printed the outer walls out silky smooth
I also use a Raft for bed adhesion but also reduced it to 5mm around the outside which provides a smooth almost ironed first layer on the raft surface when removed, The other walls all end up having straight linear print except the top but if needed could be ironed.
I also use the 'Cubic' Infill as this further provides strength in all directions X,Y & Z axis iin the print and made it 50% infill.
I used the 'Touch Builtplate' support as it only needs this to support the angled tapered section that goes up to the handle and does not print any support inside the slot where the alloy flat bar goes at all as the print will easily bridge across the 3mm top of that slot so does not need any support there.
