Open air glass top risers.
A lot of the risers out there can cost up to or more than 500g of filament , this entire set of risers is only 45g of filament and prints in 1.5hrs
Raised high enough to keep the ptfe tube from rubbing on the top of the glass and causing damage
I printed in Basic Black PETG and added a Brim to the front riser which was printed on its side, the back 2 risers do not need any brim to print.
The front riser is not my design, I created the back 2 risers from scratch to match the same height of the front riser. The front riser original design is on printable by MG at the link below
