Sprint Rack

This design has not been tested long term.  Use at your own risk.

Benefits
1) get my counter space back
2) can slide out the bottom tank without lifting everything else
3) lids should stay flatter and cleaner without another tank on top of them

This is a very large print.  It's 265x205mm in size.  FDM is highly recommended.  PETG best, PLA+ may be substituted, but it's more brittle. 

How to print this with a large FDM printer:

Purchase two Rubbermaid Twin Track rails of the same length:

The 25" rail is pictured and will hold 6 shelves.

This is a very high precision project, at least by DIY Weekend Warrior Standards.  Do not attempt unless you are very comfortable.  Use wall anchors if you are in drywall without a stud.

Mount the rails 244mm apart, center to center.  That's 9.6"  To facilitate this, print two or more of the included mounting braces.  They will hold the bars parallel while you mark your screw holes.  Tape a bubble level to the mounting brace while mounting.  Parallel mounting is VERY IMPORTANT.  If you are even 2mm off on any one screw, your shelves with bow.  They will still work, but they will not be straight.   

Print the flex shelves.  If you have PERFECT rail mounting, you can print the stiff shelves.  They will take a lot longer than the flex shelves.  The breakage point on both is still the same clasp.  Do not bear down on the shelves or load them with any weight beyond a print tank and resin.

Make sure the shelves are fully seated into the track before loading.  Test with empty resin tanks to make sure its secure and can withstand weight before loading with resin laden tanks.

How to DIY this without a 3d printer

Cut wood shelves to 260mm x 188mm (10.2"x 7.4").  If you cut particle board, make sure to edge tape the rough sides to prevent scrapes and sawdust.

If you are really comfortable, route two troughs for the rails to slide in

Mount two shelf tracks on the wall

Mount the brackets to the tracks and screw in your wood shelves
