MiniKossel 220mm bedbracket by richardtracy

Last crawled date: 3 years ago

The idea was I wanted as much printing area as possible for my FLSun Mini Kossel, but also have a heated bed with insulation and glass top (eventually with PEI as well). The mounting holes in the bed took up more space than I wanted and could only use three of them which made the bed uneven and flexible. I couldn't put the glass bed flush without removing them. The bed now lays flat on the base with no springs.
Coming soon:
taller versions added to support bed screws head clearance and help with warping when heating and cooling the brackets from the bed.
Needed Items:
12 M4x14mm Hex Socket Cap Head screws (http://r.ebay.com/l3QTm3)
12 M4 2020 CNC nuts (http://r.ebay.com/7efBo9)
12 M4 washers (optional). stops the screws heads from digging in the bracket mounts
6 M4 x 20 Hex Socket Cap Head screws (http://r.ebay.com/l3QTm3)
6 M4 square nuts (I used what came with FLSun)

3 M4x30mm Hex Socket Cap Head screws (http://r.ebay.com/l3QTm3)

6 M3x10mm or M3x12mm (optional) - used on taller version; meant to hold bed in place
I provided many different options.
MiniKossel_bedbracket_press_v5.stl (optional). Used to pushed the brackets to tighten the bed; also helps even the bed out.
MiniKossel_bedbracket_clamp_bedonly_v2.stl - if using just the 220m bed
MiniKossel_bedbracket_clamp_220BedCorkGlass_v5.stl - if you have cork and glass top for the bed
MiniKossel_bedbracket_clamp_220BedCork_v5.stl - just the cork and bed clamp; may have to flip upside down (when mounting) depending on cork thickness
MiniKossel_bedbracket_bracket_front_v3.stl - print two (for the front)
MiniKossel_bedbracket_bracket_v3.stl (for the back)
