Glass plate/Mirror bed holder

Work in progress.. I have to test the heat resistance of different plastics in order to better adjust the parts thickness. And check the weight added to the heatbed. If the weight of the set is too important, I would look for another solution. ***

V.0.1

PLA

Results:

• No good result with standard PLA. I can not increase the thickness in x axis of the supports to resist heat distortion without the supports touching the gantry rails.

Weight:

• 1 "heavy" angle holder + clamping plate, weighs 19g => 19 * 4 = 76g.
• 1 "heavy" side holder + clamping plate, weighs 33g => 33 * 4 = 132g.

So the complete set of "heavy" parts weighs 208g (7.337 Oz). (weight of screws not included) Design:

• if you use big wheel for bed leveling, it can be difficult to access the screw's heads
• Thickness in x axis of the supports can't be increased to resist heat distortion without the supports touching the gantry rails.
• Screws wear out their supports and it is possible that they do not tighten sufficiently. I will try with M4 screws.

Todo:

• Move screws holes location.
• Try with M4 screws.
• Try with High grade PLA.
• Forget PLA and do it in PTEG.
• Measure the screws weight.

ABS

Results:

• Not tested yet.

Weight:

• 1 "heavy" angle holder + clamping plate, weighs 15g ? => 15 * 4 = 60g.
• 1 "heavy" side holder + clamping plate, weighs 29g ? => 29 * 4 = 116g.

So the complete set of "heavy" parts weighs 176g (6.208 Oz). (weight of screws not included) Design:

• *if you use big wheel for bed leveling, it can be difficult to access the screw's heads.
