Super Drum 70 Tpu Bumper

Made a tpu bumper for the Super Drum 70. From initial tests seems good for around 1.5m drops consistently.

Designed with uneven ground in mind, which is why it encompasses the bottom third of the drum.

Print tpu bumper with 2 walls or less, if you are fancy you could remove bottom and top layers but will need a modifier for where the hardware goes through. You will require supports (yes you can use supports with tpu) to where the screws meet the flat part of the bumper, just use minimum tree support and should be fine.

Print rearBody as normal, only thing changed is 2 brass heat inserts added.

Only hardware required is:

• 2 x M3 brass inserts (4mm OD, under 5mm Length)
• 2 x M3 x 10-15mm SHCS (any length in that range should be fine, as well as the diameter of the head us under most M3 SHCS)

Most likely will have to sand the meeting surface flush after pressing inserts in if there is excessive plastic.

I have only broken one feed lips (shortest neck) from a drop of 2m and had a pretty bad flip. Just keep that in mind that i just chucked all the slots in cause it seemed like that would be effective at absorbing the fall.

PLEASE DON'T HAVE A SOOK AT ME BECAUSE THE BUMPER DIDN'T SAVE THE NECK OR DAMAGED YOUR DRUM. THIS IS JUST PEACE OF MIND AND TO HELP MITIGATE DAMAGE TO THE DRUM ITSELF FROM ACCIDENTAL DROPS. 

PLEASE USE AT YOUR OWN RISK.

Provided .step files if you want to edit, but they are pretty cactus.

If you are actually competent at CAD please make a better version, this is more just a stop gap for people to use until a better one is made. 

Cheers.
