One issue with the Tarot 280 quad frame is that the power distribution board is open and on the bottom of the frame where it may get damaged so ive designed this printable cover.
There are 2 versions
the standard version requires 4 nos replacement M2.5 X 8mm allen head bolts
the other version doesnt require bolts ( file name ends in >NB = No Bolts) and is a push fit over the bolt heads but may require double sided tape on the frame or a couple of drops of glue on the bolt heads to secure.
It may fit the 250 as well but i have no way of chcecking as i only own the 280. Ive included a basic hole position dimension drawing if youd like to check.
